Hi there..just added two new chickens to my existing bunch. (Yes I quarantined.) So my BO doesn't want to come out of the coop. She just hangs out in there roosting and walking around. Is it because she is new and scared of the others? The others haven't really picked on her. The leghorn and her are friends. The leghorn hasn't been afraid and is down in the run with the others? She is healthy. Ideas?
