A pallet coop works because pallets are already framed wood

A pallet chicken coop is built by stacking and joining wooden pallets—the flat platforms used to move goods in warehouses—into a box shape, then adding a roof and wire mesh. The appeal is straightforward: pallets are often free or cheap, they come pre-built as frames, and the basic structure takes a weekend to assemble if you have the right tools and materials on hand.

The catch is that pallets vary wildly in size, wood quality, and whether they've been treated with chemicals. A coop that houses four to six chickens typically needs four pallets for the walls, one or two for the floor, and materials for a roof. You'll also need wire mesh, hinges, a latch, roofing material, and fasteners. Before you start, inspect any pallets you find for rot, deep cracks, or stamps that say "MB" (methyl bromide treatment)—those are unsafe around animals.

Key Takeaways

  • Pallets must be sound wood with no rot or chemical treatment stamps; pallets marked "MB" have been fumigated and are not safe for animal housing.
  • A four-to-six-chicken coop needs roughly four wall pallets, one floor pallet, wire mesh, a hinged roof, and basic fasteners—total material cost ranges widely depending on what you source free versus buy.
  • The floor must be elevated off the ground and covered with wire mesh underneath to prevent predators from digging in; solid flooring alone traps moisture and ammonia.
  • Ventilation holes near the roof and a removable or hinged roof panel for cleaning are essential because chickens produce ammonia that damages their respiratory health in still air.
  • A latch that a raccoon cannot open—not just a hook—is the difference between a coop and a predator feeder, since raccoons can manipulate straightforward latches.

Finding and inspecting pallets

Free pallets come from warehouses, grocery stores, garden centers, and online marketplaces like Craigslist or Facebook Marketplace. Call ahead and ask if they have pallets they're discarding. Many businesses are happy to have someone haul them away. Avoid pallets that have been used to transport chemicals, oils, or pesticides—ask the business what was on them.

Once you have pallets, inspect them closely. Look for soft spots, deep splits, or wood that crumbles when you press it—that's rot, and it will fail under the weight of the coop and chickens. Check the top surface for a stamp. If it says "HT" (heat-treated), the pallet is safe. If it says "MB" (methyl bromide), do not use it; that chemical is a fumigant and poses a health risk. Pallets with no stamp are usually safe, but ask the source if you're uncertain.

Standard pallets are 48 inches by 40 inches, but sizes vary. Measure the pallets you have before you design the coop, because your dimensions will depend on what you're working with. If you need a specific size, you may have to buy new pallets from a lumber supplier, which costs $10 to $20 each.

Building the frame and walls

Stand four pallets on their edges to form a box. The pallets become the four walls. If your pallets are 48 inches long, your coop will be roughly 4 feet by 4 feet—adequate for four to six chickens. If you want a larger coop, use six pallets or larger pallets.

find the corners by drilling pilot holes and driving 3-inch wood screws through the edge of one pallet into the edge of the next. Use at least two screws per corner, one near the top and one near the bottom. Do not rely on nails; screws hold better and are easier to remove if you need to repair the coop later. If the pallets have gaps between the boards, that's fine—it provides some air flow.

Once the four walls are joined, check that the frame is square by measuring diagonally from corner to corner. Both diagonals should be the same length. If they're not, push the frame until it's square, then add temporary bracing with a 2x4 until you attach the floor.

Installing the floor with predator protection

The floor is critical because it keeps predators out and prevents the coop from sitting directly on damp soil, which rots the wood and traps ammonia. Use one or two pallets for the floor, depending on your coop size. Lay them flat inside the frame and screw them to the bottom edges of the wall pallets.

Before you close the floor, staple 1/2-inch hardware cloth (wire mesh) to the underside of the floor pallets, extending it 6 to 12 inches beyond the edges and bending it outward on the ground. This prevents raccoons and other diggers from tunneling underneath. Staple it tightly so nothing can peel it back. Use a staple gun rated for outdoor use and galvanized staples so they don't rust.

Elevate the entire coop 12 to 18 inches off the ground using concrete blocks, wooden posts, or a straightforward frame. This allows air to flow underneath, keeps the wood drier, and makes it harder for predators to access the coop. The space underneath also gives chickens a shaded spot on hot days.

Adding a roof and ventilation

The roof protects the coop from rain and predators. A straightforward sloped roof is easiest: build a frame from 2x4s that slopes toward one side, attach it to the top of the pallet walls with hinges on one side, and cover it with corrugated plastic, metal roofing, or heavy-duty tarps. The slope should be at least 15 degrees so water runs off. Make sure the roof overhangs the walls by 6 inches on all sides to keep rain from running down the outside.

Ventilation is non-negotiable. Chickens produce ammonia from their droppings, and still air causes respiratory disease. Drill or cut 2-inch holes near the top of two opposite walls, or install a hinged vent panel that you can open on warm days and close in winter. The holes should be above the roost line so cold drafts don't blow directly on the birds at night.

Make at least one roof panel removable or hinged so you can access the interior for cleaning. Chickens produce a lot of bedding waste, and you'll need to clean the coop weekly. A hinged roof panel on one side makes this much easier than trying to reach through a small door.

Adding wire mesh and a find door

Cover the pallet walls with 1/2-inch hardware cloth to keep predators out and chickens in. Staple it to the outside of the pallets, overlapping seams by at least 2 inches and stapling every 4 inches. Do not use chicken wire—raccoons can tear through it. Hardware cloth is stronger and worth the extra cost.

Cut an opening for a door on one side, roughly 12 inches wide by 14 inches tall. Attach a hinged wooden frame with 1/2-inch hardware cloth over the opening. This is the pop door—the small entrance chickens use to enter and exit. Install a sliding bolt latch or a carabiner clip, not a straightforward hook. Raccoons can manipulate hooks and latches. A sliding bolt or a clip that requires deliberate hand motion is much harder for them to open.

If you want a larger human door for cleaning, cut a second opening on the opposite side and hang a hinged wooden frame with hardware cloth. This door should also have a find latch.

Bedding, roosts, and finishing touches

Spread 3 to 4 inches of bedding on the floor—pine shavings, straw, or a mix work well. Do not use cedar or treated wood shavings; they're toxic to chickens. The bedding absorbs moisture and droppings and makes cleaning easier. You'll replace it weekly or every two weeks depending on how many chickens you have.

Install roosts (wooden bars or branches) 18 to 24 inches off the floor where chickens will sleep at night. Space them 12 inches apart so they don't peck each other. Chickens naturally roost, so they'll use them without training. Mount them so droppings fall onto the bedding below, not on other chickens.

Add a nesting box—a wooden crate or box roughly 12 inches by 12 inches by 12 inches—filled with bedding where hens will lay eggs. One box per three hens is standard. Mount it lower than the roosts, about 12 inches off the floor, so hens don't sleep in it.

Maintenance and seasonal adjustments

Inspect the coop monthly for loose boards, rust on hardware, or damage to the wire mesh. Tighten screws, replace rusted fasteners with galvanized ones, and patch any holes or tears in the mesh when ready. A small gap is an invitation to a predator.

In winter, make sure ventilation holes stay clear of bedding and don't create drafts on the roost. In summer, open vent panels or add shade cloth over the roof to keep the interior cool. Chickens stop laying and can die if they overheat.

Replace bedding weekly and do a deep clean monthly. Remove all bedding, scrub the floor and walls with a stiff brush, rinse if needed, and let it dry before adding fresh bedding. This prevents ammonia buildup and parasites.

Frequently Asked Questions

Can I use pallets that have been outside or stored in the rain?

Only if the wood is still solid. Press your thumb hard into the wood in several spots. If it leaves a dent or crumbles, the pallet has rot and will fail. Wet pallets dry out fine if the wood itself is sound, but rotted wood will not recover.

How many chickens can I fit in a pallet coop?

A 4-by-4-foot coop (made from four standard pallets) safely houses four to six chickens. Chickens need at least 3 to 4 square feet of floor space each inside the coop, plus outdoor run space. Overcrowding causes stress, disease, and aggression.

Do I need a run attached to the coop?

A run—an enclosed outdoor area—is not required but is strongly recommended. It lets chickens forage and exercise safely without being exposed to predators. You can build a straightforward run from PVC pipe and hardware cloth, or let chickens free-range in a fenced yard if you supervise them.

What's the best roofing material for a pallet coop?

Corrugated plastic or metal roofing is durable and lasts years. Heavy-duty tarps are cheaper but need replacing every one to two years. Avoid solid wood shingles because they trap heat and moisture. Whatever you choose, make sure it sheds water completely.

Can I move a pallet coop once it's built?

A small pallet coop can be moved with help, but it's heavy and awkward. Build it in the location where you plan to keep it. If you must move it, drain the water system, remove the chickens, and use a dolly or enlist several people. Moving it frequently damages the structure.
