I've recently removed my Silver Gray Dorking from the flock of 9 hens and 2 other roosters. The hens(not the rooster) viciously attacked Alvins tail to the point where he had no pin feathers and exposed flesh. I was mortified by what his bottom looked like. Luckily it did not effect him using the bathroom. We made a makeshift home for him in our garage. About a week later the hens targeted the other rooster, Sal. I took him out of the coop to freerange around the yard for a couple of days to see if things would heal. While he was out, They targeted my third rooster, Little Roo. I don't know what to do. All hens, especially the Rhode Island Red's just don't leave them alone. I love having the roosters because i love hatching my own eggs in the Springtime. ANY SUGGESTIONS????
