We just moved our 10 -11 week pullets & one cockerel to the adult coop in a temporary pen where they can get aquanted. A few weeks ago, a neighbors roo decided he was going to adopt our adult hens and start living with them in our coop. This wasn't a problem until we moved the pullets & cockerel to the temp pen in the coop on Saturday. When the rooster goes in for the night, he makes such a fuss that it get's the pullets all worked up and they pile on top of each other because they get scared and freaked out. Saturday night, my husband pulled one of the pullets from the bottom of the pile, it appeard to be dead, on it's back and feet up. He brought it outside and it came back to life. The rooster got locked outside for the night, our yard is fully fenced, he keeps coming back by jumping over the fence. We don't mind him, but again tonight he caused the pullets to freak out. He isn't our rooster, we don't mind him staying unless he keeps disturbing the new pullets, any advice on how to keep things calm? If he continues to cause a frenzy with our new babies and if we can't get rid of him, then it will leave us with only one option since he won't go home and the owners a few houses down has several roosters and they don't lock them up or keep them fenced in their yard. Any advice would be greatly appreciated.
