My wonderful husband is building me a coop but thinks its too big for 4 chickens. its 4x4x4 coop, and 16 ft run plus 4 ft under the coop. my question is, its this too big? because if it is, that means I could get more chickens right? lol. I don't think this is what he thought of when he said it was too big but I want more then 4 chickens lol.
