In my head I see my coop (for 24 hens and 1 rooster) 36 ft long (to accomodate 24 nesting boxes 18 x 18), 6 ft high:1 ft off the ground for nesting boxes, 2 ft head clearance with the roost at about 3.5 ft off of the ground (to accommodate the nesting boxes and head space) and 2.5 ft for head space. I'm thinking about 5 or 10 ft wide for the coop itself plus an additional 10 ft for the chicken yard. I imagine that my mothers will probably stay in their nests, so their half would have a skylight and my egg layers hlaf would be next to the garden so they can do bug patrol. I'm not sure of what to do with the rooster because I know he has to be separated from the brooders while they are incubating but I dont think I can have a friend for him because they'll fight (he will have about 4 ft wide for himself when he isnt breeding). I read that hens use the same nesting box but wont those nesting need their own nest box? If I can cut down on the number of nesting boxes on the egg layers side, that would be awesome. I hope this is clear; thank for the input!
