What You Get From Pallets and What You'll Need to Add

A pallet coop works because pallets are already framed wood in a useful size — typically 48 inches by 40 inches — so you skip the step of cutting and framing from raw lumber. Four to six pallets can form the walls and floor of a small coop for three to six chickens. What pallets do not give you is a roof, hardware cloth to keep predators out, hinges for nest boxes, or a door frame sturdy enough to swing reliably.

Before you start, inspect any pallets you find for chemical stamps. Pallets marked "HT" (heat-treated) are safe; pallets marked "MB" (methyl bromide) were treated with pesticide and should not be used for animal housing. Pallets from food suppliers, beverage distributors, and garden centers are usually HT. Pallets from chemical suppliers, paint stores, or industrial sites are often MB.

You will also need galvanized screws (not nails — nails loosen as the wood moves), a drill, a saw, hinges, a latch, roofing material (corrugated plastic, metal, or asphalt shingles), hardware cloth with a mesh size of 1/2 inch or smaller, and a staple gun. A level and a tape measure save time. Expect to spend $150 to $300 on materials beyond the pallets themselves, depending on the size you build and the roofing you choose.

Key Takeaways

  • Pallets marked "HT" are heat-treated and safe; pallets marked "MB" were treated with pesticide and should not be used.
  • A basic four-pallet coop takes one to two days to assemble and houses three to six chickens depending on how you arrange the pallets.
  • Hardware cloth stapled to the inside of the frame stops predators from reaching your birds; chicken wire alone is not strong enough.
  • The roof must overhang the walls by at least 6 inches on all sides to keep rain from running down the inside during storms.
  • A hinged roof or removable top panel makes cleaning and egg collection much faster than a fixed roof.

Laying Out the Floor and Walls

Start by deciding whether you want a fixed coop or a mobile one. A fixed coop sits in one spot; a mobile coop has wheels or skids so you can move it to fresh ground. Mobile coops are lighter (usually three to four pallets) and prevent the ground underneath from becoming compacted and filthy. Fixed coops can be larger and more stable, but they need good drainage underneath or the bedding will stay wet.

Lay two pallets flat on the ground, parallel to each other, about 3 feet apart. These form the floor frame. If the ground is uneven, use a level and shim with wood scraps under the pallets until they are flat. Uneven floors cause doors to stick and water to pool. Screw the two floor pallets together at the corners using galvanized screws — three screws per corner, driven through the frame of one pallet into the frame of the other.

Stand two more pallets upright on the floor pallets, one at each end, to form the back and front walls. Screw these to the floor pallets at all four corners. If you want a coop taller than a single pallet (about 40 inches), stand a third pallet on top of the first, creating a wall roughly 80 inches tall. Screw the upper pallet to the lower one at the corners and at the center where the frames overlap.

Securing the Frame and Adding Hardware Cloth

Once the walls are standing, brace them against wind and the weight of chickens jumping inside. Screw a diagonal brace from the top corner of one wall to the bottom corner of the opposite wall on both the inside and outside. Use 2-by-4 lumber cut to length, or use scrap pallet wood if it is straight enough. Brace the sides the same way if you have added a third pallet to the height.

Staple hardware cloth to the inside of every wall, floor, and any openings. Start at the top and work down, pulling the cloth tight as you go. Overlap seams by at least 2 inches and staple through the overlap. Hardware cloth with 1/2-inch mesh stops rats and weasels; 1-inch mesh stops larger predators but allows smaller ones through. Chickens will peck at the cloth, so fold the bottom edge inward and bury it 6 inches into the ground if the coop is fixed, or staple it to the underside of the floor pallets if the coop is mobile.

Do not skip the hardware cloth on the floor. Predators dig from underneath. If you are building a mobile coop, staple cloth to the underside of the floor pallets as well. If you are building a fixed coop and the ground is soft, dig a shallow trench around the perimeter, lay the cloth in it, and cover it with soil.

Building and Hanging the Roof

The roof is the most important part for keeping the coop dry. It must slope so water runs off, and it must overhang the walls by at least 6 inches on all sides. A straightforward roof is two pieces of plywood or corrugated plastic laid on top of the walls at an angle, meeting at a peak in the middle. A flatter roof is easier to build but collects water; a steeper roof sheds water faster but is harder to access for cleaning.

Build a frame for the roof using 2-by-4 lumber or pallet wood. The frame should be slightly wider than the coop (to create the overhang) and long enough to span from front to back. Attach the frame to the top of the walls with hinges on one side so the roof can open for cleaning and egg collection. Attach a prop stick or a chain to hold the roof open at a safe angle. Lay roofing material over the frame — corrugated plastic is light and cheap, metal is durable, asphalt shingles are traditional but heavier.

Seal the seams where the roof meets the walls with caulk or flashing so rain does not run down the inside. If you use corrugated plastic, seal the top edges with trim so water does not pool in the corrugations. Test the roof by pouring water on it and watching where it runs; adjust the slope or add flashing if water is running toward the coop instead of away from it.

Adding a Door and Ventilation

Cut a door opening in one of the walls, roughly 12 inches wide by 14 inches tall — large enough for a chicken to walk through without stooping. Frame the opening with 2-by-4 lumber screwed to the pallet frame. Hang a door using hinges, and add a latch that closes securely. The latch must be strong enough that a raccoon cannot open it by pulling or twisting. A slide bolt or a carabiner clip works better than a straightforward hook-and-eye.

Ventilation prevents moisture and ammonia from building up inside, which causes respiratory disease. Drill or cut a vent hole near the top of each wall, roughly 4 inches by 4 inches. Cover the vent with hardware cloth so predators cannot reach through. If the coop is in a cold climate, you can close the vents in winter with hinged panels, but do not seal them completely — chickens need air movement even in cold weather.

Building Nest Boxes and Roosts

Nest boxes are where hens lay eggs. Build them from scrap pallet wood or plywood, roughly 12 inches wide by 12 inches deep by 12 inches tall. Mount them on the inside wall, about 2 feet off the ground. One nest box serves two to three hens. A coop for six chickens needs two to three boxes. Line the boxes with straw or wood shavings so eggs do not crack.

Roosts are where chickens sleep. They prefer to roost high, so install a roost bar (a 2-by-2 or a branch) about 2 feet off the ground, running the length of the coop. Space multiple roosts 12 inches apart vertically so chickens do not poop on each other. Mount the roost so it is straightforward to clean underneath — a removable tray under the roost catches droppings and makes cleaning faster.

Finishing and Weatherproofing

Sand any rough edges on the pallets so chickens do not get splinters. Paint or stain the exterior to protect the wood from weather, but use only non-toxic finishes — chickens will peck at the wood and ingest whatever coating you use. Linseed oil or exterior wood stain rated for animal contact are safe choices. Do not paint the interior where chickens spend time.

Check the coop for gaps where predators could squeeze through. Pallets are not always perfectly square, so gaps appear where they meet. Seal gaps with hardware cloth stapled over the opening, or fill them with wood filler and sand smooth. Pay special attention to corners and the junction where the roof meets the walls.

If you built a fixed coop, add a ramp from the door to the ground so chickens can walk in and out without jumping. A straightforward ramp is a piece of plywood with cleats screwed across it for grip. If you built a mobile coop, add wheels or skids to the underside of the floor pallets so you can move it by hand or with a small tractor.

Frequently Asked Questions

How many chickens can I fit in a four-pallet coop?

A coop made from four pallets (roughly 8 feet by 4 feet) comfortably houses three to four chickens. Chickens need about 3 to 4 square feet of floor space each inside the coop, and about 8 to 10 square feet each in an outdoor run. Overcrowding causes fighting, disease, and dirty conditions.

Can I use pallets that have been outside or used for shipping?

Yes, as long as they are marked "HT" (heat-treated). Pallets used for food, beverages, or garden supplies are usually HT. Pallets from industrial or chemical suppliers may be marked "MB" (methyl bromide) and should not be used. If a pallet has no marking, assume it is not safe for animal housing.

Do I need a predator-proof run attached to the coop?

A run is not required, but it is strongly recommended. A run is an enclosed outdoor area where chickens can scratch and forage while protected from hawks and ground predators. Without a run, chickens must stay inside the coop most of the day, which leads to boredom and fighting. A straightforward run is four pallets stood on edge and covered with hardware cloth.

How often do I need to clean a pallet coop?

Remove droppings from under the roost and soiled bedding from the floor at least twice a week. Replace all bedding completely once a month, or more often if the coop smells like ammonia. A hinged roof or removable top makes cleaning much faster and easier than a fixed roof.

Will a pallet coop last more than one season?

Pallets exposed to weather will rot within two to three years without treatment. Paint or stain the exterior with a non-toxic finish to extend the life to five to seven years. Replace any pallet boards that become soft or splintered. A well-maintained pallet coop can last as long as a coop built from new lumber.
