A 5-gallon bucket on its side makes a fine nest box. That isn’t just a homestead hack, either. Oregon State’s extension service calls the bucket “a creative alternative to the traditional wooden nesting box” in its coop design guide.
What nobody hands you is the bucket’s own numbers. So I did that part, and honestly it’s kinda simple arithmetic. I read 18 sources for this, most of them state extension services, plus one supplier’s spec sheet for a food-grade pail, and held the bucket up against the nest box they all describe. It mostly fits. It’s tight in one spot, and the sources flat out disagree on one rule you’ve probably seen repeated everywhere.

Two Extension Services Already Name the Bucket
Oregon State is one. The University of Florida is the other. Its guide to raising hens for eggs says a wide range of materials can be reused for nests, “including repurposed buckets or milk crates.”
That’s about where the endorsement stops. Neither one gives you a bucket plan. Every number they publish is for a box, so the rest of this post takes their box rules and checks the bucket against each one.
So what does a bucket get you over a box? It’s cheap and it’s light. It’s also one piece, with no seam where two boards meet, and you’ll see why I care about that once we get to mites.
Does a 5-Gallon Bucket Measure Up to a 12-Inch Box?
The box most guides draw is a cube. Kentucky’s extension says nest boxes are “typically 12 inches wide x 12 inches high x 12 inches deep” and Oregon State gives the same 12 by 12 by 12. Colorado State says that size should fit most breeds. Utah State runs roomier, 12 to 15 inches high and wide and at least 12 deep. Maryland goes small, 10 by 10.
Now the bucket. The food-grade pail I looked up is listed at 11.9 inches across and 14.56 inches tall. Lay it on its side and the mouth is your opening, about 12 inches across. The length turns into depth, about 14 and a half inches. It narrows a little toward the bottom, like every bucket does.
So on paper you’ve got a 12-inch nest with extra depth. Pretty good for a bucket.
Here’s the tight spot. A round bucket has no flat floor. The bedding sits in the curve, and every inch of it comes off the top. Put in 3 inches and you’ve got about 9 inches between the bedding and the roof of the bucket. That’s the same as a 12-inch box with 3 inches in it, so the difference is the shape. In the bucket you only get that 9 inches at the middle, because the roof curves down toward the sides, and the bedding is about 10 inches wide across the top instead of 12. That’s my arithmetic, not a source’s, and none of them give a head room number I could check it against.
What they do say is about big birds. Tennessee’s extension says “Larger breeds may require a slightly larger box” and NC State says a 12 by 14 inch nest should be big enough for any breed. If you keep a large, heavy breed, I’d hang one bucket and watch her use it before you build a whole wall of them.
Only a Bucket That Held Food
This is the one rule here I’d call a must. Use a new bucket sold as food-grade, or one you know held food. Not a drywall mud bucket. Not a pool chemical bucket. Not the mystery one behind the shed.
The University of Arkansas extension explains why, in a page about reusing containers: “Many plastics pick up small amounts of the substances stored in them and release them later.” Its example is plain enough. Don’t keep dry cereal in a laundry detergent bucket. A nest box isn’t a cereal bin, but a hen sits in it to lay and your eggs lie right on it. I’d hold it to the same rule.
The number on the bottom doesn’t settle it by itself, either. Maryland’s extension lists #2 plastic (HDPE) as one of the safe ones, but it says repurposed containers should be rated food-grade in the first place. The pail I looked up is HDPE marked #2, and it’s sold as FDA compliant for direct food contact. When I checked on October 25, 2026, it was $5.93 a bucket, six to a case.
If somebody offers you a free one, ask what was in it. Food, fine. Anything else, or nobody knows, pass.
How Many Buckets Your Flock Needs
Fewer than you’d guess. Most of the sources land on one nest for every four or five hens:
- Oregon State: one for about every four birds
- NC State and Utah State: one for every four to five
- Georgia and Maryland: the same, four to five
- Florida: at least one for every five
- Kentucky: one for every five, and never fewer than two per flock
- Colorado State and Wisconsin: one for every three to four
- Tennessee: one for every four to six
- Penn State: two for the first four hens, then one more for every four after that
So if you’ve got 6 hens, most of them say 2 buckets. Penn State’s rule, rounded up, says 3. For 12 hens you’re at 3 by most of the list and 4 by Penn State’s.
The ratios assume hens take turns. If you see a line forming anyway, move up to the most generous rule on the list. With a small flock that’s Penn State’s, and with a big one it’s Colorado State’s one for every three.
The Roost Rule the Sources Split On
You’ll read this one everywhere. Put the nests lower than the roosts, because chickens sleep on the highest thing in the coop. The old version of this post said it. Our own coop calculator says it too.
The University of Maryland agrees. Its housing page says “Keep roosts higher than the nesting boxes.” A few lines up on the same page, though, it says nest boxes and roosts should both sit 24 inches above the floor.
Here’s the thing. Two other extension services say the opposite. NC State says to place the roosts “below the entrance level of the nests” and Oregon State says to avoid putting nest boxes lower than the roosting poles, because it keeps the boxes cleaner.
Penn State skips the height fight and uses distance. Nests at least 2 feet off the ground and at least 4 feet away from the roosts. Its roosts go 18 to 24 inches above the floor, so by its numbers the nests end up level with the roosts or a little above them.
Turns out they do agree on the part you actually care about. Keep the nests apart from the roost, so nobody sleeps in a bucket and fills it with droppings overnight. Penn State keeps its roosts away from the nests for that reason. Birds that end up sleeping in the boxes will “quickly contaminate your nesting boxes and increase egg breakage and dirty eggs,” in its words.
If young birds keep sleeping in the buckets anyway, Colorado State has the simplest fix I found, and you don’t have to rebuild anything. Close the nests off at night while pullets are learning, so they have to use the roost, then open them in the morning. A scrap board over the row of bucket mouths does it. For the roost itself, the bar spacing and heights are in 6 chicken roost ideas and the numbers behind them.
A Lip, a Landing Pole and a Dark Corner
The box guides keep mentioning a few small things, and your bucket needs each of them.
The lip first. Penn State wants “a three to four inch lip” across the front to hold the nesting material in, and Utah State a front panel 4 to 6 inches high, which also keeps eggs from rolling out. On a bucket you can get that two ways. Snap the lid on and cut the opening in its upper part, so a solid strip of lid stays at the bottom. Or leave the lid off and screw a board across the bottom of the mouth. Either way, sand the cut edge smooth.
Then somewhere to land. Kentucky says a nest box off the floor should have a perch in front of it, so hens can get in and out “without breaking eggs.” Oregon State says one pole along a row of boxes works, and Georgia calls it a place for hens to land before they go in.
And the dark corner. NC State says nests belong at the back of the coop, away from windows, because hens prefer darker areas for nesting. Penn State and Virginia say the same thing, and Tennessee says to keep the nest out of direct sun. So if you were planning to hang a white bucket under the window, I’d pick another wall.
One more if you stack them. Colorado State, NC State, Oregon State and Kansas State all say to slope the top of the nests so birds can’t roost up there and mess in the box below. Oregon State’s slope is 45 degrees. A board at that angle over the top row of buckets does the job.
How Much Bedding Goes in the Curve
Here the sources are all over the place. Maryland says 1 to 2 inches of clean, dry straw or pine shavings. Penn State says 2. Utah State says at least 2 to 3. Kansas State says several inches, and NC State’s front board holds a 6-inch layer.
The reason is the same in every one of them. Bedding cushions the egg. Penn State puts it bluntly: “Many eggs are cracked due to a lack of protective padding in nesting boxes.” Utah State adds that it cuts down on soiled eggs.
In a bucket I’d stay at the low end, 2 to 3 inches, and that’s just me reading the shape. The curve already gathers the bedding into a dip in the middle, and that dip is where an egg rolls to. Every inch more comes straight off that 9 inches of head room.
Straw or wood chips both work, by Wisconsin’s guide, and Colorado State says straw or shavings. The part people skip is Kansas State’s: clean and dry. Its guide on hens that eat eggs says nesting material with broken egg on it should come out and be replaced.
If your hens ignore the new buckets, Florida’s guide says a ceramic or wooden egg in the nest can help.
Cleaning a Bucket, and Where Mites Hide
This is where a bucket earns its keep. Florida and Colorado State say to clean the nests once a week, Wisconsin too, and Virginia says to clean them out and put in fresh litter at least every two weeks. You lift a bucket off its bracket and tip it out, then wash it. Try that with a plywood box screwed into the wall. It’s a total pain.
For the washing, Maryland’s extension gives a routine for reusing food-grade containers in the garden. Soap and water, 10 minutes in a 10 percent bleach solution, then wash and rinse again and let it air dry. It’s written for planting buckets, not nests, but it’s a sound way to clean one.
Now the mites. The University of Florida’s page on the chicken mite, also called the poultry red mite or roost mite, says that when they aren’t feeding, they hide in cracks and crevices. Nests and litter too. They rarely feed by day, they lay their eggs right where they hide, and the whole life cycle can finish in as few as seven days.
So fewer seams means fewer places to hide. That’s the honest case for plastic over plywood. Don’t call a bucket mite-proof, though. The rolled rim is a crevice. So is the edge of the lid, and any crack in old plastic. Florida says to look for mites at night, on the birds, or to search the nests and any cracks. When you do, check your bucket rims too.
A Bucket Won’t Stop a Raccoon
Look, a nest box is furniture. It isn’t predator protection, and nothing you do to a bucket changes that.
Raccoons want the eggs as well as the birds. Maryland’s predator guide says they steal eggs, and that they’re smart enough to open simple latches, so lock the doors. New Hampshire Fish and Game says raccoons reach through bigger mesh to grab poultry, and that 1/4-inch hardware cloth keeps out even the small predators. It also says to bury hardware cloth 12 inches deep around the pen against the ones that dig.
So fix the coop and the run first. Then worry about where the eggs land. Collecting twice a day, which is what Virginia and Wisconsin both say, leaves less sitting in the nest for anything to find. I went through why in how long eggs can stay in the coop, and there’s more on the hardware itself in predator proof coop ideas.
