What number would you be comfortable at with these coop dimensions? My husband and I are not agreeing on this. The main coop is 8x8 that houses all roost bars. A smaller structure sits directly behind it that's 4x4 with a window and the nestboxes and a small door that my kids go to, to collect eggs. So overall 8x8+4x4 gives me 80 square feet. We also have an 8x 24 run attached to the front. How many hens would you feel comfortable keeping in there?
