Brought six new chickens home, 2 silkies, 2 Amercaunas and 2 smaller birds but they haven't been welcomed very well. The two groups were separate all day on different sides of a fairly large run.. original birds were 2 Leggorns, a Buff Orpingtom and a Rock. The leghorns have been especially mean actually forcing one of the Ameracaunas to stay in the coop, every time she came out they would jump on her and force her back in.. So tonight we come home and all the new chickens are roosting in the run and all the original chickens are in the coop roosting.. not ONE new bird is in the coop. Should I be worried?
