soooo.....I've got this rooster who's extra friendly....to humans. He is really rough on the girls, though. He's very aggressive, and grabs them by the neck (no gentle pecking) before mating. Most of the hens are missing feathers on their necks, backs, and rumps. Found one of my hens with a broken neck the one morning, and suspect his overzealous advances. He is the only rooster in the flock, was raised right here from an egg, and has 18 hens with him. He was never exposed to another rooster for "proper" training. They are cooped at night, and free-range in a 1/4 acre fenced pasture with lots of tasty weeds, clippings, crumbs, etc. tossed in, along with their layer feed. Is there ANYTHING I can do to make him less rough on the girls, besides getting him out of there? Thanks!
