So I took one of the 4.5 week old chicks to the coop to meet the rooster. He immediately attacked her and chased her around until I could get him away from her. He pulled out some feathers, but other than that she seems okay. My intent was to move all the chicks to the coop today, but now they're back in the brooder until I can figure out what to do. The rooster was protective of his other flock, so I thought he'd be happy for some company. HELP!
