We have 6 chicks we hatched 2 weeks ago. Last night one of the chicks started picking on one of the others. The chick went after the same chick over and over and became more aggressive over night. By this morning we knew something had to be done...the chick would corner the other and grab it by the neck or wing and come away with the a mouth full of feathers. The poor abused chick couldn't get to food or water and was huddling behind the other chicks or in the corner. We decided to separate the bully into his own brooder. The jailed chick complained and complained so we decided to put another chick in there because we figured he was lonely. After that peace on the home front. How long should I keep this bully separate from the other chicks?
