This is my idea of a breeder/brooder coop. The smaller pens will be doubled, one on top of another, with solid bottoms on the upper cages, so nobody gets poopy heads. The bottom pens will have access to the runs. These will be for bantam sized chickens, either trios or maybe 3 hens and one roo. The uppers will be for quail and young chicks, with no run access. The two larger pens on the end will be for my game chickens. Between myself and my dad we have 1 roo and 4 hens. I will also be getting BLRW in the spring, so one large pen will be for them as well. These pens will go all the way to the ceiling. I would do no more than 4 chickens in the smaller ones like mine, and no more than 5 in the larger ones. Whatdya think? EDIT: The actual size of the building is 10'x12'
