Hi, I have recently added a rooster to our flock. We started with 10 chickens then added 8 more plus him. They've been together for about a month now. However our rooster is being picked on by some of the chickens. He hides under our nesting boxes and usually only comes out at night. Today we went in amd noticed how rough he is looking. He is missing feathers off the back of his neck as well as most of his feathers on his head which we call his "hair" as he's a golden polish rooster. Does anyone have any suggestions on what could be going on? Not sure if we should find out which one it is and get rid of it or if it'll get better.
