Guys I have pullets that are about 12 weeks old and I bought an adult rooster to help protect them after I lost a hen to a predator. I got a rooster and kept him separated from them for about 2 weeks to get them used to him. They could see each other through a fence that touched. Now everytime I let the rooster out with the hens he chases them around and terrorizes them and tries to breed with them. Should I just let him? The hens also won't eat or drink while he's around and they hide in the coop from him. Not sure what to do here.
