I have 1 dominique, 1 barred rock, and 2 golden buffs that lived together their whole lives. Just a few days ago I got 2 Ameraucanas. The golden buffs keep pecking at the ameraucanas. A few days ago, we went outside to check on the chickens and there was black feathers everywhere from one of the ameraucanas. Also, today one of the GB (lily) was in the nesting box making really loud noises. she laid an egg. I think it was only her 2nd one. Since she is new to the egg laying, does that have anything to do with her behavior to the new chickens?
