I'm confused, why only 1 nest per 4 hens? and I would like to know how many hens can I fit into my chicken tractor, it is 4'x4'x4' and the nests are 22" from the floor. The run is, 12'L x 4'W x 3' H and 4' of that is under the coop area and closed in on 3 sides. Can I get 6 americauna hens and 1 rooster into that area? Some say 2sqft per bird others say 4 but I understand this also has something to do with the run area. And how many nest? Sorry for the dumb questions. Ed.
