A very aggressive rooster--who has since moved on to another home--managed to rake off many of the back feathers to several of my hens, and although the worst victims have since replaced most of their feathers, a Buff Orpington still walks around with a very bare and unsightly back. I think she's getting sunburned! We've watched closely and can see no signs of pecking from others in the flock. Our current rooster doesn't seem to be nearly as rough. This has been the situation for the last 5 months. Any suggestions?
