We have a silky rooster that is not really an aggressive one and he's so not that big. He has been beating up on a younger silke rooster. This one is missing most of his feathers on his head. Then recently he has been, I guess attacking (have not actually witnessed) our other rooster which is a very large rooster. The big ones head is a little bit bloody now. We have close to 40 chickens total so I dont think its an issue with too many roosters. But we're not sure if this is just a pecking order thing and it will subside or if we need to get rid of the silky.
