For now, my chickens (all adults - 11 hens, 1 rooster)are stuck in a 6 x 10 run or so, and a giant breed wire kennel for their "coop". They have all been getting along fine until yesterday (brought them home last sunday), when I came home after dark and saw feathers all over the coop. Scared me at first, as there was only 6 in the kennel, but found the rest perched on top of the kennel. When I went out this morning, I noticed one who's tail feathers were sparce, and loose feathers on the body also. I managed to catch her, and put her in a crate with straw and food for now. Should I just put her back in there and let them work it out? or what? Any idea if this behavior from the other hens will subside after we get their big coop finished and a better run for them? New to this whole chicken thing .. . . now if it was dogs, I would know what to do. Help!
