My Auracans all are losing feathers in their saddle areas. Its really cold here in Michigan, and I worried about them. My husband is sure it is caused by our overly zealous roo. He's ready to cull him from our flock. Can this be the cause? Is there anything I can do for them, or feed to them, to help them get their feathers back faster? I'd hate to have to give up the roo. I have two of them and they make a great hen-guarding team!
