All of my 6 Easter Eggers are doing great! All are eating and drinking, but one is kinda a outsider. It eats and drinks and runs around and is healthy but he doesn't really interact with the others much. He was hatched with three siblings at the same time so it's not like he was alone for a long time. It likes to pick on the other chicks. Is that why? Or is he male? They were just hatched not even 24 hours ago. And we handle them and everything. Any thoughts why he is a outcast?
