We got out chicks about a week and a half ago. All of our other chicks are playing fine but Omlet (who was growing normally and seemed fine) won't wake up today even when she was picked up. She has been peeping for a while now and 2 hours ago she was favoring her left foot. I thought she was alright but tired because she would still open her eyes and respond. Is there anything we can do? I would feel awful if she passed away and I could have done something.
