I have an Easter Egger (Gizmo) rooster who was hatched the first week of May. For the last 2 weeks, he has been breeding my 8 hens like crazy. He can't go 5 minutes without jumping one of them. Even the underage pullets. It's really stressing them out, and he's really rough. I have 2 other roosters in the flock, one who is the same age and hardly ever breeds (he's shy). The other is the oldest and flock leader, but doesn't mate much either. Whenever Gizmo mates one of the hens, then hen screams in distress, and the flock leader runs over and beats up Gizmo. What should I do???
