I am looking at some coops that are I guess you could say prefab... Its a kit actually, they're made locally and seem to be pretty good quality. My question though is about square foot per bird. I have read that you will want 2 sq ft per bird. Is that inside the hen house only or also including the run? Do you include the nesting boxes in the calculation? The coop I'm looking at says it's for 6-8 birds (the people who make them also raise chickens) but if I look at the square footage just of the hen house and not including the nesting boxes, it seems it would be better for only 3-4 chickens. Square footage of hen house only (without nesting boxes) is about 7.5 sq ft. Hen house plus run (without nesting boxes) brings it up to about 30 sq ft . I guess the nesting boxes would add about 2-3 more sq ft... So what do you think? Could I put 6 birds (mix of Ameracauna, Plymouth rock, Welsummer, Australorp) in there or closer to 4?
