Key facts every chicken keeper should know before building a coop.
Standard-size chickens need at least 4 square feet of coop floor space each. Overcrowding causes stress, feather pecking, and reduced egg production.
Outdoor run areas should provide at least 10 square feet per chicken. More space means happier chickens and less ground damage from scratching.
You don't need a nesting box for every hen. Chickens naturally share, and 1 box for every 3-4 hens is the recommended standard for optimal laying.
Chickens sleep on roosting bars. Standard breeds need 8-10 inches each, while larger breeds may need up to 12 inches of roosting bar space.
Proper ventilation prevents moisture build-up, ammonia, and respiratory disease. Aim for 1 square foot of ventilation per 10 sq ft of floor space.
Use hardware cloth (not chicken wire) with openings no larger than ½ inch. Bury wire 12 inches deep around the run perimeter to deter digging predators.
