Okay...Early spring I bought an older black polish Hen with the funky head feathers...I slowly put her into the group of girls and things worked out okay....IN April I got a free Rooster(first one) ...came with the horse we bought for DD....He totally pecked off her head feathers ...I seperated them and he would just go nuts trying to get at her....needless to say he became a fine tasting broth for my neighbour down the road....then I had 5 americana eggs hatch out and one was a rooster....they have all been together over the last 22 weeks everything was fine until this week...I noticed my roo trying to impress the girls with a dance and puffing his feathers and now HE"S picking on my polish hen...chasing her back into the coop....what should I do? I have no other coop with a run .I do have a large dog cage that i used before to seperate the birds.MY other chickens are white leghorns and sex links and RIR crosses..19 hens and one roo
