I'm in the process of figuring out what coop size to build. I'm reading everywhere that I need X square feet per bird. For the sake of the calculation let's say 4 square feet per bird. Let's say I want to have 3 chickens. The next thing I'm reading everywhere is that that calculation is 4 feet X 3 birds, or 12 square feet of floor space for my coop. I'm thinking that is incorrect. I'm thinking it's 4 feet X 4 feet (four square feet) x 3 birds or 48 square feet of floor space. Am I crazy? Bottom line I think I need to build a coop with a floor space that is 6 X 8 feet (48 square feet). Anyone else out there having problems understanding this chicken math?
