Just got three teenager banties (5-6 week olds) and one mama with a 5 day old chick. They had all been living together in a HUGE coop/pen/run, and now moved to my smaller one at home. I kept them all enclosed in the coop from about 4:00pm yesterday til this morning so they would know this was their return/safe place. I let them out this morning, but the mama hen is picking on the older three. She seem to run them out of the coop right away. Is this establishing pecking order? or should I be concerned. I did go out and make sure they can go up the ramp back into the coop, but she bullied them out again. They survived the night together okay and I've seen them all eat and of course POOP. Any thoughts or opinions would be GREATLY appreciated.
