I've been trying to intoduce my chicks to the rest of our flock for a while now. Unfortunately, when we let them loose, the rooster tries mating the pullets. I'm afraid he is going to injure them as he's already been somewhat aggressive with them and they are nowhere near big enough to put up with him. The older hens don't bother them much, but are also "over handled" by the rooster. Our easter-egger has hardly any feathers on her back and one of the others has started going bare as well. We are currently down to only 6 hens, one rooster, and 11 chicks about 9 weeks old (all are supposed to be pullets, but we'll see). Any suggestions?
