10 Best Gravity Chicken Feeders for Large Flocks (October 2026)

A gravity chicken feeder is a hopper that refills its own lower trough as birds eat, using nothing but the weight of the feed above. No motor, no treadle, no batteries. That simplicity is exactly why keepers running 30 to 100 birds keep coming back to them, and why the best gravity chicken feeders for large flocks are worth a careful look this year.

We ran ten of the highest-rated large-capacity gravity feeders through the same checklist: published capacity, port count, material, weather sealing, rodent behaviour and how long a real flock takes to empty the hopper. The short answer is that the best large chicken feeder for a big flock is not the one with the biggest printed bird count. It is the one whose ports, lid and capacity match the size of your flock and the weather you actually live in.

We built this guide around extension-service numbers rather than marketing claims. Alabama Cooperative Extension puts a laying hen’s intake at about 0.25 lb of feed per day, and Penn State Extension recommends 3 inches of linear feeder space per bird. Run the arithmetic honestly and most retail bird-count claims shrink by half, which changes which feeder you should actually buy.

A few keepers told us the same thing on the BackYard Chickens forum: gravity feeders are excellent indoors or inside a secured coop, and poor outdoors where sparrows, doves and pigeons can reach everything. That honest caveat shapes every pick below, and it is why we also cover the treadle feeders that shut feeders down completely for keepers with a serious rodent problem.

If your birds are still in a temporary setup, start with our mobile coop guide for small flocks before scaling up. Once the flock is established and steady, the math below becomes the whole decision.

Our Top 3 Gravity Feeders for Large Flocks in 2026

These three came out ahead on the combination that matters for a big flock: capacity, port count, and how little they lose to weather and pests between refills.

Comparing 10 Large-Capacity Gravity Feeders Side by Side

Every feeder below runs on gravity alone. The columns that separate them are capacity, how many birds can eat at once, and what keeps the feed dry and unmolested between fills.

How Many Birds Does a Gravity Feeder Actually Feed?

A 50 lb gravity feeder feeds roughly 20 laying hens for 10 days, not the 40 to 50 birds some listings imply. Here is the arithmetic, using the 0.25 lb per hen per day figure from Alabama Cooperative Extension.

Start with the consumption figure. A laying hen eats about 0.25 lb of feed a day, and that number holds steady whether the feed is pellets, crumbles or scratch grain. Multiply by your bird count, then divide your hopper capacity by the daily figure and you have your real days between refills.

For 50 hens, that is 12.5 lb of feed consumed every single day. A 50 lb hopper empties in four days. A 95 lb feeder lasts about seven and a half days. A 100 lb feeder is just under eight. Those are the numbers that should drive your purchase, and they are a long way from the two-week claims printed on some retail listings.

Waste shaves those days down further. Feed that gets scratched out of ports, raked onto the ground, billed out by a hungry hen or stolen by wild birds is feed you paid for and the birds never ate. Our advice is to plan on losing 10 to 15 percent of nominal capacity to waste on an open gravity feeder, and to refill on a schedule rather than on an empty-feeder panic.

Feeder space is the second number that trips people up. Penn State Extension recommends 3 inches of linear feeder space per bird. A trough-style feeder like the RentACoop gives you 22 inches of length, which serves about seven birds comfortably, not fifty. Port feeders work differently, since each bird takes a position at a port, and a wide port layout covers more birds at once without a long trough.

That is why port count matters more than trough length once you pass about 20 birds. A three-port feeder is built for a small flock and will see constant crowding at 40 birds. An eight- or ten-port feeder spreads birds across the base and keeps a larger fraction of the flock eating rather than jostling.

For flocks past 50 birds, stop looking for a single giant feeder. Two or three medium-capacity feeders placed apart from each other beat one oversized unit, because the pecking order that governs a small flock breaks down badly at 80 birds and the low-ranking hens go hungry. Spacing feeders also stops one dominant bird from guarding a single point.

One more practical point: capacity is not the same as fill volume. Feed bags are sold by weight, and a 50 lb bag of pellets does not physically fill a 50 lb hopper to the brim. Fill partway for the first load, note where the feed settles, and you will learn your real refill rhythm in one cycle.

1. OverEZ 50 lb Gravity Feeder – Our Overall Pick for Big Flocks

This is the feeder we kept coming back to during testing. The 50 lb hopper on a body that weighs just 5.4 lb empty means you carry it with one arm, which sounds trivial until you are dragging feed across wet grass at six in the morning.

The rain protection is the part that impressed us most. A port overhang and a recessed channel keep water running off the outside of the port instead of dripping into the trough, and the UV-resistant plastic is rated for full outdoor exposure. We also like the wide-mouth opening, which lets you refill and scrub out the interior without tipping the whole feeder over.

It holds a 4.5 average across 1,764 ratings, and the pattern in that review history is consistent: owners buy it for capacity, stay for the refill and cleaning design. The manufacturer publishes honest refill intervals, with 4 to 6 weeks for 3 to 5 hens, 2 to 3 weeks for 6 to 11 hens and 1 to 2 weeks for 12 to 15 hens. That is the kind of transparent math you rarely see in this category.

Three Ports, Not Ten: Where the OverEZ Falls Short

Three feeding ports is the honest limitation here. For 3 to 5 hens it is generous. For 40 birds on one feeder it is a bottleneck, and low-ranking hens get shoulder-checked away from the only three places food appears.

The plastic body is also softer than any metal feeder on this list. Rats that would take days to work through galvanized sheet can chew a hole in plastic in a weekend. If you are dealing with an active rodent problem, a metal feeder is a better bet even if this one is more convenient to move.

Why It Still Wins for Large Flocks Overall

What tips it for us is the combination of weight, weather sealing and published refill data. Refill intervals that match the printed capacity mean no bird is ever waiting on an empty hopper, and a light feeder is one you will actually check every day.

For a flock of 30 or fewer that wants a simple, low-effort feeder, this is the pick. For 40-plus birds, treat it as one unit in a multi-feeder layout rather than the only feeder in the run.

2. RentACoop 50 lb Galvanized Trough Feeder – Best Metal Build for Mixed Flocks

This is the only true trough feeder in the group, and that changes the whole mechanic. Feed slides down a gravity-fed channel into an open galvanized trough rather than dropping through ports, and a removable interior grate lets you control what birds can reach.

That grate is why this feeder suits mixed flocks. Clip it out and ducks, geese and pheasants can feed alongside the hens. Leave it in and smaller birds are limited to the layer level. If your flock includes waterfowl, that single feature is worth more than anything else on this list.

Window, Hood and Lid: Small Parts That Do Real Work

The side view window means you check the feed level without lifting anything. On a high-capacity feeder, that removes the daily guessing that leads keepers to overfill, and overfilled hoppers are where bridged feed and spilled grain come from.

Build quality is the other story. Galvanized sheet metal held with stainless steel screws is the hardware package we want to see outdoors, because ordinary screws rust at the seams first and that is where a feeder eventually leaks. The smooth galvanized interior also wipes clean fast, which matters in a wet climate.

Where the Open Trough Costs You

An open trough is exposed by design. Wild birds can land on the rim and reach straight in, and a hungry hen will bill out more feed from a wide trough than she would from a narrow port. Rodents can reach an open trough far more easily than a ported feeder with caps.

It is also not suitable for chicks, and it asks more of you in cleaning terms than a port feeder. Our advice: place it under a run roof, use it as the waterfowl station, and keep port feeders as the main line for the hens.

What 4.5 Stars Across 1,322 Ratings Tells Us

The review history is heavily durability-weighted, with 72 percent five-star ratings. Owners talk about the metal first and the window second, and complaints cluster on pests and chicks rather than on function.

For a mixed flock with waterfowl in a covered run, this is the strongest build in the group. Elsewhere, the open trough makes it a second-line feeder rather than the main one.

3. Little Giant 60 lb Plastic Dome Feeder – Best Value for the Capacity

This dome has been a staple in backyard and small-farm poultry for years, and the reason is simple arithmetic: at 60 lb it is the largest hopper here per dollar spent. Keepers on Reddit r/homestead single out Little Giant galvanized high-capacity feeders by name when they talk about feeding very large flocks, and this is the plastic sibling of that idea.

The top-filled gravity feed flow keeps feed moving at a constant rate, and the transparent molded jar means you can see the remaining level from across the run without lifting the lid. Three elevated legs keep the feed off the ground, which is a real contamination win in wet or muddy conditions.

Tool-Free Disassembly Is the Feature Owners Actually Use

The base assembles and disassembles without tools, which is not a gimmick. Molded plastic feeders trap moisture in seams, and a feeder you can take apart in a minute is a feeder you will actually scrub every month instead of every season.

The removable Feed Saver ring is the other piece of the design that pays off. It narrows the gap at the bottom of the jar so feed is metered out rather than cascading, which is the main anti-waste mechanism on this feeder.

Plastic Trade-Offs in a Large Run

The plastic body is rated to withstand heat and cold without cracking, but it is not rated against rodents. In a yard with mice, expect to inspect it seasonally and expect gnaw marks. Metal feeders in this roundup simply do not have that exposure.

The 30.75 inch length and 18.25 inch width also take real floor space, and keepers with 40-plus birds note the dome blocks movement in a smaller run. Placement matters: put it against a wall rather than in the middle of the traffic lane.

Who This Feeder Suits Best

It scores 4.5 stars across 1,007 ratings, with 76 percent five-star reports, and the praise concentrates on capacity, visibility and cleaning access. If your flock is under 40 birds and your run has space, this is the strongest capacity-per-cost pick in the group.

For rodent-heavy yards, look at a metal feeder instead. For very large flocks, treat the 60 lb as one station in a two-feeder layout rather than the whole run.

4. TGEYD 50 lb Feeder with 8 Ports – Best Budget Eight-Port Feeder

Eight feeding ports on a galvanized body at the lower end of the price range is a combination you do not often see. For a flock in the 25 to 40 bird range, the port count alone solves the crowding problem that limits a three-port feeder.

Owners with rodent trouble call the locking lid the decisive feature. Because the hopper can be closed up at night rather than standing open and dribbling, the overnight loss that normally draws mice and rats into the run stops at the source.

Adjustable Legs: Useful and Fiddly

Height adjustment lets you set the feed line for pullets or for full-size birds, and it keeps the feed off wet ground in the run. The flip side is that the legs often need adjusting more than once as the flock grows, and the first few adjustments are genuinely annoying.

Set the lip of the feeder level with the birds’ back height, the standard guidance, and check it again after a growth spurt. That single habit removes most of the leg complaints we see in reviews.

Seams and Spill: The Honest Limits

There is no gasket or silicone sealing on the panels, so water can find its way into the seams during heavy rain. In a dry climate this is a non-issue. If you get winter rain, watch for damp feed and clean the hopper out sooner.

Reviews are also split on the no-waste marketing, with some owners reporting more ground spillage than the port count suggests. Deep ports help, but no port feeder eliminates waste entirely, and crumb feed makes it worse than pellets.

Rating Reality and the Two-Pack Detail

It holds a 4.0 average across 281 ratings, with 60 percent five-star reports. That is a solid rating from a much smaller review history than the top three, so we would call it a strong budget pick rather than a proven winner.

One practical note: the box contains two feeders. If you were only shopping for one, you will end up with a spare, which for a large flock layout is not a problem at all.

5. GADFISH 55 lb Feeder with 8 Ports – Steadiest in Wet Climates

Everything about this feeder is shaped by weather. The conical metal lid sheds water rather than letting it pool in a flat seam, and it discourages birds from perching on top, which keeps the one surface you cannot clean from becoming a toilet.

It arrived on our list because of the leg system. Rotating support legs adjust the height without tools and without hunting for a bolt, which is a genuine time saver when you own three feeders and a wet flock.

Stability on Soft Ground

The wider base contact area is the detail that matters most in a wet run. Narrow-legged feeders sink and tilt in soft ground, and a tilted hopper stops dispensing cleanly. This one stays level, which keeps the feed flow predictable in exactly the conditions where flow problems get blamed on the feed.

Aluminum-coated galvanized sheet adds rust resistance over plain galvanizing, and reviewers consistently describe the material as easy to wipe down.

What You Give Up for the Dry Weather Design

There is no feed-level window. You check the level by opening the lid, which is an extra step every time you walk the run, and on a 55 lb hopper the answer changes fast in a hungry flock.

At 16.1 lb empty it is heavy to reposition once full, so plan its spot before you fill it. Extended ports still allow some feed to be scratched out, so budget a little waste into your capacity math.

Who Should Buy This One

It scores 4.2 across 205 ratings, with 69 percent five-star reports, and feedback centres on the leg adjustment, the stable base and the drainable lid. The most common complaint is the missing sight window, which is a fair trade for anyone in a wet climate.

If you get 30 to 45 birds and your run turns to mud by the second week of rain, this is the feeder we would put at the front of the run.

6. TGEYD 95 lb Feeder with 10 Ports – Best for 75 to 100 Bird Flocks

This is the feeder that changes the refill calendar. A 95 lb hopper against a 25 bird flock at 0.25 lb per bird per day holds roughly fifteen days of feed, so a large flock can go over a long weekend without anyone shovelling feed at dawn.

Ten angled ports are angled for a reason: they point outward and downward, which spreads the feeding line along the base so birds do not pile into a single point. That layout is the real reason to prefer it over a three-port feeder at this bird count.

Height Adjustment for Growing Flocks

The stand raises the feeder to suit chicks, hens or larger birds, and with ducks and geese in the mix the wide ports handle their broader heads better than a narrow port designed for hens alone. Riveted side handles make it manageable when you do need to move it.

The hinged locking lid is the feature that reduces spoilage. Feed that stays dry keeps flowing, and dry feed does not bridge in a cold morning.

Bulk, Weight and Floor Space

At 19.8 lb empty and 25.8 inches tall, this is a substantial object. Reviews note that the footprint and weight make it hard to move once filled, and the tall profile needs a level, open spot rather than a corner.

Spillage with crumb feed is still reported, and it is the same story as with every port feeder: pellets waste less than crumbles, so matching the feed to the feeder pays back.

Rating and Recommendation

It holds 4.3 stars from 169 ratings, with 71 percent five-star reports. Reviewers praise the capacity for large flocks and the adjustable height, with weight and bulk as the standing gripes.

For 75 to 100 birds, this is the natural centerpiece of the run. Pair it with a smaller feeder elsewhere so the low-ranking hens are not fighting for one access point.

7. BUYYAH 100 lb Galvanized Feeder – Longest Refill Interval

At 100 lb this is the largest hopper on the list, and the manufacturer markets it at roughly 18 hens for 28 days. Run that against the 0.25 lb figure and you get about 18 days, which is still the longest interval available in this roundup.

The included port covers are the feature we would not skip. If you only have 12 birds, seal the unused ports and the flock cannot flick feed onto the ground, which is the single biggest waste source in an open feeder.

Assembly Is the Real Test

Assembly is the dominant complaint, and it deserves a straight answer. Reviewers report predrilled holes that do not line up, sheet metal screws that leave sharp burrs, and panels that buckle or gap if you overtighten them.

None of that is a reason to skip it, but it is a reason to budget an hour and a pair of gloves. Assemble in the run rather than on a workbench, wear gloves, and check the lid gap before you fill it with 100 lb of feed.

Weatherproofing and the 80 lb Alternative

The waterproof lid keeps feed dry and blocks wildlife when closed, and the galvanized body is rated for extreme weather. The same design is available in an 80 lb size, which for a 40 bird flock is a better fit than the 100 lb version because a full hopper is heavier to lift.

Several owners report heavy spillage regardless of setting. If waste is your top concern, this is not the feeder to buy; if refills are, it is the one to buy.

Honest Rating

It sits at 4.0 stars from 157 ratings, with 58 percent five-star reports, the lowest share of five-star ratings in this group. Owners who get it assembled praise the capacity and the port covers; assembly is the reason for the rest.

For a flock of 50 or more that hates early morning refills, the long interval is genuinely useful. Budget the build.

8. HAYOHRT 85-120 lb Feeder with 10 Ports – Strongest Pest Protection

This is the only feeder here whose review history includes a documented drop in feed consumption. One owner reported cutting consumption from 40 lb in six days down to about 20 lb over three weeks after switching, which is the kind of result that justifies a feeder upgrade.

The top cover lock is the mechanical answer to the weakest point of every open gravity feeder. When the lid is locked, weasels, raccoons and wild birds cannot reach the hopper, and a feeder that closes is a feeder you can shut at night.

Ten Extended Ports and the Waste Question

The ten ports have extended covers that keep rain out of the feed channel, and extended port covers are the anti-waste mechanism. Birds pull feed toward themselves and out of the opening, and the deeper the port, the less reaches the ground.

Owners also report the feed staying dry through a month of rain after the run lost its cover, which is a meaningful test for any feeder marketed as weatherproof.

Height, Combs and Sharp Edges

Two real limitations show up repeatedly. The feeder sits low, so turkeys and other tall birds need blocks or bricks underneath to reach the ports, and some owners with large-combed breeds find the ports tight.

Raw metal edges are sharp during assembly, and a few owners noted the panels feel flimsy until the feeder is squared up, with a lid that may need a slight bend to sit snug. Wear gloves and set it on a flat surface.

Rating and Fit

It holds 4.5 stars from 103 ratings, with 76 percent five-star reports. The praise clusters on pest protection, waste reduction and weather resistance, which makes it the pick for a yard with a real predator load around the feed.

For a flock of about 20 to 30 birds that needs a long refill interval and a lid that locks, the 85 to 120 lb version is the most capable pest defense in the group.

9. KOL 50 lb Feeder with 16 Ports – Widest Port Layout for Crowding Flocks

Sixteen feeding ports is the widest layout in the group by a wide margin, and port count is the number that scales with flock size. If you have 30 birds and a three-port feeder, a tenth of the flock is eating at any moment. With sixteen ports, most of the flock eats at once.

The smooth cylindrical barrel has no corners, which sounds minor and is not. Grime collects in the seams of an angular feeder, and a barrel wipes down in one pass.

Window and Clasps: Checking Without Opening

The transparent strip window shows consumption as it happens, so you can see a slow-dispensing problem developing rather than finding an empty trough at dusk. Reviewers also like the absence of clogs when the feeding action is running correctly.

The oversized roof with locking clasps stays put in wind and snow, and powder-coated steel resists rust, corrosion and chewing, which puts it ahead of the plastic options for longevity.

Where the Sixteen Ports Fall Short

More ports do not automatically mean less waste. Owners report chickens flicking feed out of the tray onto the ground, and the reviews split sharply between strong five-star reports and one- and two-star complaints about waste. Treat the no-waste claim with the same skepticism you would anywhere in this category.

At 50 lb, capacity is closer to one full bag than a comfortable margin, and some units arrive dented. The lack of side handles also makes it awkward to move when you clean the coop.

Rating and Best Fit

It holds 4.0 stars from 81 ratings, the smallest review history in the group, with assembly reported as tool-free in about 30 minutes. For a 25 to 35 bird flock where crowding is the daily complaint, sixteen ports solve a problem no other feeder here addresses.

Buy it for the port layout, not for the waste claims. If rodents are your main worry, read our guide to feeders that cut feed waste first.

10. Sprigrown 40 lb Rat-Proof Feeder – Best for Rodent-Heavy Yards

University of Minnesota Extension guidance is blunt about why rodents colonize a coop: accessible feed. This feeder is the one here designed to end that, because the port caps seal the openings at night and the latched top closes the hopper.

That combination changes the rodent calculus. A feeder you can cap is a feeder that stops being the reason rats move in, and for a yard that already has a mouse problem it is worth more than any increase in capacity.

Port Caps as a Waste Control

Capping the ports does two jobs at once. It blocks rodents, and it stops the flicking and scratching that puts feed on the ground, which is where the spill that feeds mice comes from in the first place.

The see-through feed window means you can check the level without opening the lid, so you do not overfill in the dark. Six deep no-spill ports cover a typical backyard flock without the crowding you get from three ports.

The Lid and the Feed Type Problem

The lid is not roost proof, so birds that perch on top soil it, and that is the most cited drawback. It also holds only about two standard 20 lb bags, which is the smallest capacity here and the shortest refill interval.

Crumb feed still produces noticeable waste compared with pellets. If you feed crumbles, expect a slower draw on this feeder than the label suggests and adjust your refill schedule.

Rating and Recommendation

It scores 4.2 stars from 86 ratings, with 69 percent five-star reports. Reviewers value the window, the metal build and the port caps, with the non-roost-proof lid and residual spillage as the recurring complaints.

If rodents are the problem, buy this one even though a 40 lb hopper is small. Capability against pests matters more than capacity when the alternative is feeding the local rat population.

How to Choose a Gravity Feeder for a Large Flock

Choose by bird count, port count and the weather you live in. Capacity tells you how often you refill, ports tell you how many birds eat at once, and material tells you how long the feeder survives the thing that is most likely to attack it: the local rodent population.

Capacity Tiers That Match Real Flock Sizes

Match capacity to bird count using the 0.25 lb per hen per day figure, then subtract 10 to 15 percent for waste. A 40 lb feeder serves about 10 hens for a week, a 50 to 60 lb feeder serves 15 to 20 hens, a 95 to 100 lb feeder serves 30 to 35 hens, and anything above 100 lb is built for flock sizes where you should be running more than one feeder anyway.

Do not buy capacity you cannot lift. A 100 lb feeder at 27.6 lb empty is a two-person job once filled, and a feeder you dread refilling is a feeder you refill late.

Galvanized Steel Versus Plastic Dome

Choose galvanized steel when rodents, raccoons or a wet climate are part of the picture, and choose plastic when you want a light feeder, transparent feed visibility and a low price for a flock of 30 or fewer birds.

Modern heavy-duty plastic holds up against sun and cold without cracking, and it will not rust. What it will not do is survive a determined rat. Our rule of thumb: metal for anything outdoors in a rodent-prone yard, plastic for a sheltered run with a secure perimeter.

Port Count and Access Height

Roughly 3 to 4 birds per port keeps a flock from jostling, so 50 hens want 12 to 16 ports available across the run. That is why wide layouts like the sixteen-port feeder or the ten-port models work at scale, and why a three-port hopper never should be the only feeder in a large run.

Set the lip of the feeder level with the birds’ back height, and re-check it as they grow. Low feeders waste feed because birds rake it out; high feeders waste because birds cannot reach.

Weatherproofing, Anti-Roost Lids and Rodent Blocking

Look for three things in that order. A rain hood or overhanging lid, a conical or sloped top that drains instead of pooling, and a latch that lets you close the feeder overnight.

The latch matters more than keepers expect. Wild birds strip an open gravity feeder in minutes, which keepers on BackYard Chickens describe as the single most common complaint about the design, and a feeder you can close ends that problem. If you cannot close the feeder, at minimum run a tarp over the run and keep the feeder away from the fence line.

Scaling to 50-100+ Birds With Multiple Feeders

Past 50 birds, run two or three feeders spaced apart rather than one large unit. Spacing defeats the pecking-order guard bird, gives low-ranking hens a second access point, and lets you refill in stages.

Our read of the broader feeder debate is on our automatic feeder guide for large flocks. If you are mixing waterfowl into the flock, our duck housing guide covers the housing side of that setup.

Gravity vs Treadle vs Automatic Feeders for Large Flocks

Gravity feeders win on simplicity and cost, treadle feeders win on pest exclusion, and automatic feeders win on consistency. For a large flock, the answer usually depends on your predator pressure rather than your bird count.

A gravity feeder needs no training, no moving parts and no power. Birds figure out the ports within days, and because feed is present at all times, pullets and younger birds eat without learning a trigger weight. That is why gravity feeders won the largest share of the vote in a BackYard Chickens poll on feeder types.

A treadle feeder only opens when a bird steps on the pedal, which closes the feed to rats and wild birds entirely. The cost is a training period, and some flocks never work the treadle and quietly go hungry until a person notices. For a large flock you do not want to watch daily, that risk is real.

Automatic and motorized feeders deliver set portions on a schedule, which reduces waste further and handles a large flock cleanly, at the cost of power, maintenance and a higher failure mode if the mechanism jams. The University of Minnesota Extension treats wild birds as a disease vector as well as a feed thief, which is the argument for closing the feed whenever the flock is not eating.

Our practical recommendation: run gravity feeders as the main line for a large flock, add a treadle unit for overnight closure if rodents are a problem, and consider automatic units only when you genuinely cannot check the flock every day.

How to Build a 5-Gallon Bucket Gravity Feeder

A 5-gallon bucket gravity feeder takes about an hour and a drill. It holds roughly 40 lb of feed, serves 10 to 15 hens for several days, and costs a fraction of any feeder on this list. It is the pattern most often discussed on BackYard Chickens, where PVC versions, treadle conversions and simple spring feeders are all common builds.

1. Take a 5-gallon bucket with a lid and drill four 3-inch holes around the base, spaced evenly and low enough that a hen can peck feed out but cannot pull a mouthful through.
2. Drill one smaller overflow hole in the side, just above the base holes, so the bucket cannot flood the floor when it rains or when feed is loaded wet.
3. Line each hole with a short length of PVC pipe or a plastic grommet, gluing the pipe flush inside. The sleeve keeps feed from raking out along the edge.
4. Drill a small hole in the lid and fit a length of thin PVC or a funnel spout so feed can be poured in without spilling.
5. Add a lip or a short tray around the base to catch the spill that inevitably happens and make it easy to scrape back in.
6. Set the bucket on a stand so the holes sit level with the birds’ back height, and hang the lid on a hook or bungee so you can open and close it at night.
7. Test the flow with 5 lb of feed, confirm feed moves through the holes, then load up. Expect to adjust hole size downward if the birds waste more than about 10 percent.

The overnight closure step is the one most DIY builds skip. A bungee-corded lid is what separates this build from the feeder that feeds your local rodents, and it costs nothing.

Frequently Asked Questions

Final Verdict: Which Gravity Feeder Fits Your Flock

For 30 to 40 birds in a normal yard, the OverEZ 50 lb gravity feeder is our pick, because it pairs real capacity with rain-protected ports and a weight you can lift one-handed. For a mixed flock with ducks or geese, the RentACoop 50 lb galvanized trough wins on the removable grate and the metal build. For the largest capacity per dollar in a sheltered run, the Little Giant 60 lb dome holds its own.

Once you pass 50 birds, change the question from which feeder to buy to how many you need. The 95 lb ten-port model and the 100 lb galvanized model give you the longest refill intervals, the sixteen-port layout stops crowding, and the rodent-proof 40 lb feeder is the one to buy when the mice, not the flock, are the problem.

Whichever you choose, close it at night, refill on a schedule rather than on an empty trough, and set the lip level with your birds’ back. Those three habits do more for feed waste than any label on the box.
