Hiya, I mixed my two silkie flocks last night ready for this morning. One flock has three mature girls and the other has three girls and a rooster at 5 months, all flocks the same body size. The hens seem ok with each other- mild pecking. But my rooster is flying into wild attacks with the older girls and now he's bleeding! It only happens when I'm not there so they know who's boss. But unless I grow feathers and start laying eggs I'll have to leave them at some point! Any advice?
