Backyard Chicken Coop
A 6×3¾ ft coop for 4–6 hens — 4×4 post frame, elevated floor, shed roof, 2-bay nesting box with exterior egg door, roost bar, two rear barn doors, and a pop door with ramp.
Plan for rough-cut lumber, with actual dimensions.
Actual lumber: a 2×4 is 2 in × 4 in — found at a local private sawmill. Nominal: a 2×4 is 1.5 in × 3.5 in — found at most chain hardware/lumber stores.
A sturdy backyard coop on the same reliable 4×4 post frame as our farm stand. The floor sits 13¾” off the ground — predators can’t nest underneath and the birds get shade below. A 2-bay nesting box mounts inside the right wall with an exterior egg-collection door, so you never have to enter the coop to collect eggs. A roost bar runs side-to-side above it. The shed roof sheds rain to the back; rough-sawn vertical siding breathes naturally as the boards dry — no screened vents needed. Two full-height barn doors on the rear wall open the entire back for cleaning; a 12”×15” pop door with a ramp on the front lets the hens in and out on their own schedule. Barn-door construction on every door — planks, rails, and a Z-brace — means nothing to buy beyond lumber and hardware.
