Start with pallets and reclaimed wood to cut material costs in half

A functional chicken coop does not require new lumber or expensive kits. The cheapest route is to build from pallets — wooden shipping platforms that businesses discard — plus a few reclaimed materials. Most pallets are free or cost $5 to $10 each. You will need four to six pallets depending on coop size, plus a sheet of plywood for the floor, roofing material (corrugated plastic or old metal roofing), and hardware cloth to keep predators out. This approach costs $80 to $150 total for a coop that houses four to six chickens.

The alternative is to buy new 2x4 lumber and plywood, which runs $200 to $300 before you add roofing and wire. Pallets skip that cost entirely. Check behind grocery stores, feed suppliers, garden centers, and warehouses — ask the manager if you can take them. Avoid pallets marked with "HT" (heat-treated), which is safe; never use pallets marked "MB" (methyl bromide), a pesticide. Most unmarked pallets are heat-treated and safe for chicken housing.

Key Takeaways

  • Pallets and reclaimed wood reduce material costs to $80 to $150 for a four-chicken coop, compared to $200 to $300 for new lumber.
  • The coop needs a solid floor (plywood or pallet boards), hardware cloth on all sides to stop predators, and a roof that sheds water.
  • A basic coop is a box 4 feet long, 3 feet wide, and 3 feet tall, with a hinged roof for cleaning and egg collection.
  • Ventilation holes near the top prevent moisture buildup that causes respiratory disease; roosts and nesting boxes take up minimal space inside.
  • Paint or seal wood with non-toxic finishes to extend the coop's life, especially the floor and lower walls where moisture collects.

Gather pallets and sort them by condition

Collect four to six pallets of similar size — standard pallets are 40 inches by 48 inches. Inspect each one for rot, deep cracks, or loose boards before you take it. Pallets with soft spots or wood that crumbles when you press it will fail within a year. Pallets with a few loose nails are fine; you will reinforce them anyway.

Once home, lay pallets flat and remove any nails sticking up with a pry bar. Do not disassemble the pallets yet — you will use them as wall frames. Brush off dirt and debris. If pallets are visibly dirty or stained, spray them with a garden hose and let them dry for a day before building. Store them in a dry spot so they do not absorb moisture while you gather other materials.

Build the floor and frame in one day

Start by laying out the footprint on level ground. Mark a rectangle 4 feet by 3 feet with stakes and string. The floor is the most important part — it keeps predators out and prevents water from pooling inside. Cut a sheet of 3/4-inch plywood to fit the footprint, or use pallet boards nailed together. If using plywood, drill drainage holes every 12 inches so water does not collect.

Place the floor in the marked area. Now stand four pallets upright around the perimeter — one on each long side and one on each short side — and nail them to the floor with 3-inch nails or 2.5-inch screws. Use at least three fasteners per corner. The pallets form the four walls. If pallets are not tall enough (most are 40 to 48 inches), add a 2x4 board along the top of each wall to reach 3 feet of interior height. Brace the corners with 2x4 blocks nailed diagonally from the inside to stop the walls from racking (leaning).

Cover walls and roof with hardware cloth and roofing material

Predators — raccoons, foxes, hawks, and weasels — will tear through wood and thin wire. Use hardware cloth (a metal mesh with 1/4-inch openings), not chicken wire. Chicken wire is too flimsy. Staple hardware cloth to the outside of all four walls, starting at the bottom and overlapping each piece by 2 inches. Fold the cloth down and bury it 6 inches into the ground around the perimeter, or nail it to the floor and fold it outward — either method stops predators from digging under.

For the roof, build a straightforward peaked frame from 2x4s or use two pallets laid flat and angled. Cover the frame with corrugated plastic panels (cheapest option, $20 to $40), old metal roofing, or heavy-duty tarps. Overlap seams by at least 4 inches and seal them with roofing tape or caulk. Slope the roof so water runs off — aim for at least a 15-degree angle. Leave a 2-inch gap under the eaves on two sides for ventilation.

Add ventilation, roosts, and nesting boxes inside

Chickens produce moisture through respiration and droppings. Without ventilation, ammonia and mold build up and cause respiratory infections. Drill or cut four 3-inch holes near the top of opposite walls, one on each side. Cover each hole with hardware cloth stapled over it so predators cannot reach through. These holes let air flow without letting rain in.

Inside, install a roost — a 2x2 board or sturdy branch 18 to 24 inches off the floor — where chickens sleep at night. Mount it along one wall. Below the roost, place a droppings board (a sheet of plywood or pallet board) to catch waste and make cleaning easier. In one corner, build or place a nesting box — a wooden crate or box 12 inches by 12 inches by 12 inches, filled with straw or wood shavings. One box per three chickens is enough. Chickens will lay eggs in these boxes if they are dark and slightly isolated.

Seal wood and add a hinged roof panel for access

Paint or seal all wood surfaces with a non-toxic, exterior-grade finish. Focus on the floor and lower walls where moisture collects. Linseed oil, exterior wood stain, or non-toxic paint all work. Avoid creosote and pressure-treated lumber — both are toxic to chickens. A sealed coop lasts 5 to 7 years; an unsealed one may rot in 2 to 3 years.

Cut one section of the roof (about 2 feet by 3 feet) and hinge it so you can open it to collect eggs and clean inside. Attach the hinge with bolts or heavy-duty screws. Add a hook-and-eye latch on the outside to hold it closed. This access panel makes daily tasks much faster than climbing in through a small door.

Install a door and run (optional but recommended)

Cut a door opening 12 inches wide by 18 inches tall on one wall, near the bottom. Hinge a piece of plywood or pallet board over it and add a latch. This door lets chickens move in and out during the day. At night, close and latch it to protect them from predators.

A run — an attached wire enclosure — lets chickens forage safely during the day without building a separate structure. Build a frame from 2x2s attached to one side of the coop, cover it with hardware cloth, and add a hinged door. A 4-foot by 8-foot run costs $40 to $60 in materials and takes a few hours to build. It is not essential, but it reduces predator risk and gives chickens more space to scratch and peck.

Common mistakes that waste money or create problems

Using chicken wire instead of hardware cloth is the most expensive mistake. Raccoons tear through it in one night, and you lose your flock. Spend the extra $15 to $20 on hardware cloth. Skipping the floor or using only straw invites rats and predators to tunnel underneath — the floor is not optional. Failing to bury or fold hardware cloth around the perimeter is another common gap; predators dig under walls faster than you think.

Overcrowding causes stress, disease, and aggression. Four to six chickens need 3 to 4 square feet each inside the coop, plus more space in a run. A 4-by-3-foot coop is the minimum for four chickens; do not try to fit more. Poor ventilation leads to ammonia buildup and respiratory infections — those four holes near the top are not optional. Finally, leaving the coop open at night or failing to latch doors lets predators in. Close and latch the door every evening without exception.

Frequently Asked Questions

How much does it really cost to build a cheap coop?

A basic four-chicken coop from pallets costs $80 to $150 in materials: pallets (free to $50), plywood floor ($20 to $30), hardware cloth ($20 to $30), roofing ($15 to $25), and fasteners and hinges ($10 to $15). A new-lumber coop costs $200 to $300. Labor is your own time — expect 8 to 12 hours over a weekend.

Can I use chicken wire instead of hardware cloth?

No. Raccoons, foxes, and weasels tear through chicken wire easily. Hardware cloth with 1/4-inch openings is the only mesh that stops predators. It costs more upfront but saves your flock and the cost of replacing dead birds.

Do I need a run attached to the coop?

A run is not required, but it is worth building if you cannot supervise chickens during the day. A run lets them forage safely and reduces predator risk. Without one, keep chickens locked in the coop during the day or watch them constantly.

How often do I need to clean the coop?

Remove droppings from the roost board daily. Replace bedding (straw or shavings) in nesting boxes weekly or when visibly soiled. Do a full bedding change in the coop every two to four weeks depending on how many chickens you have and how much moisture builds up.

What if I do not have a level spot to build on?

Level the ground as much as you can with a shovel and rake. Small slopes (under 6 inches) are fine — just make sure water drains away from the coop, not toward it. If the ground is very uneven, build the floor on concrete blocks or treated posts to raise it and level the structure.
