One of my chickens has no feathers on her back or top of her wing do to my crazy roosters. So I made her, and some of the others, fleece saddles so their feathers will grow back . Just my one BR has the bare back, how long before the feathers start to grow back? I have 26 hens and 4 roo's, two(?) of these roo's will be dinner soon. How many roo's would be alright with 26 hens? The roo's are fine with each other.
