My 3 Polish girls are either broody or molting. They are not sitting on eggs or laying, but behave broody and skittish. One is molting by the handfuls. They are my roo's favorites. I guess they're not in the mood, and the roo is getting more aggressive and they run away from him, and when he catches one, he grabs their feathers with his beak and won't let go. Up till this he was a gentleman. What's up here?
