I have 16 square feet in my coop. That means I can have a max of 8 birds right? One of them is a very, very small Antwerp Quail by the way. I also have three next boxes, three roosts and a very large run.
Eight birds need 32 sq. ft. Banties usually count as half a bird. You might get by with 8 but only if they go outside every day. The 4 sq. ft. per bird is considered minimum when cooped up. Cold winters may not allow them to go out on some days. Good Luck
