I have 3 silkie roosters in my flock of 12. (had more hens, but lost them) Two of them are siblings (Zeus and Titan) born and raised in the flock and only ever mildly posture at each other. never had an issue. The third younger silkie roo I named LOKI (god of mischief). He was unintentionally purchased as a sexed chick that unfortunately wasn't a pullet! He is a beautiful, BIG boy, blue splash. I kept him because he is so pretty. He was raised by a hen in my flock, along with the other two mature males (4+ years old). Now that he is mature (1 1/2 - 2 yrs old?), he is now instigating fights with the older guys. When he starts with one, the other one always joins in. He apparently got into a fight with Zeus ( a very very calm White silkie), which left Zeus with a bloody comb. Then apparently others decided to peck at the bloody area till he was literally bald. There is a 1 inch bald strip down the middle with feathers sticking out on both sides of his head! My coop is 5 x 5 ft area with a 5 x 10 ft pen underneath, and also a 24 x 13 ft extra enclosed yard that they access everyday. I also free range in the warm spring and summer months. (Like now). Zeus is now unhappily in a wire dog crate in the pen while he heals. Once Zeus comes out of the cage, I am thinking of putting LOKI in it for a few days to maybe calm down his aggressiveness some. Any ideas would be appreciated. I am trying not to rehome LOKI but I will if I must. I also have two more pullets ( 9 weeks olds) integrating with the flock right now.
