Build it in this order

  1. 01 Legs and floor. Set 12 legs on pavers, square the beams, screw hardware cloth under the joists, then glue and screw the floor.
  2. 02 Walls. Frame each wall flat, raise it, and check plumb and both diagonals.
  3. 03 Roof. Cut one pattern rafter at 6/12, test it, then set the rest with a hurricane tie at every plate.
  4. 04 Siding, doors and vents. Side the walls, hang the doors on two-step latches and screen every vent with hardware cloth.
  5. 05 Nests, roosts and pop door. Hang the nest boxes, drop the roost bars into their cradles and fit the pop door in its guides.
  6. 06 The run. Set the posts, add the rails, wrap the mesh outside the posts, then the roof and the apron.

Questions people ask

With a run, a 8x8 coop holds 13 standard hens, 27 bantams or 11 large-breed hens at our defaults (4 sq ft per standard hen inside, after Virginia Tech and Cooperative Extension). Kept shut in all day, the same floor holds only 5 standard hens, because confined birds need about 10 sq ft each.

For 13 standard hens the run needs 130 sq ft at 10 sq ft per hen, and the plan draws it 8' x 17' (136 sq ft), 72" at the low end and 97-1/2" at the coop. Its walls are hardware cloth the full height, with a 24 in apron against digging and a covered roof against hawks.

It is a walk-in coop: 6' walls, a 30 in person door and the floor 24" off the ground on 4x4 legs. You stand inside to clean, collect eggs and fill the feeder, and the run sits along the pop door side.
