i just introduced 4 new chicks in with the flock yesterday. the new chicks are 16 weeks old and the flock is 6 months old. they did OK yesterday kind of the chicks pretty much hid for the most part. but today they seemed a little better they hid in the coop pretty much all day. so when we went to go and do some grocery shopping about an hour and a half we came home to one in the corner we thought she was dead but not shes still breathing but not looking good here are some pics how do i help her. They have been in a pen inside the run for about 2 1/2 months or so. they have ample time to adjust with each other. they also have left the others some what alone a peck here and a peck there. There are some chickens in the main flock that are missing feathers on there back but no blood.
