I have a small temporary coop that was put together out of scrap materials we had. When I free range my roos, they ussually hang around the old shed. After dark when I go out to move them back to their coop, they have been roosting on the back porch near the door. Should I clean up the shed and make a coop off that? If I do decide to get more chickens, it is fairly good sized. Or should I build a small house for them up on the porch?
