I have 11 chicks about 2 weeks old now. One of my Rhode Island Reds is pecking and sometimes scratches at the other chicks. The other chicks do not defend themselves. She has done this since the minute we brought her home. I have separated her so she does not hurt the other and she is not happy. I read it could be from stress. Is she going to snap out of it?? She is really other than that and loves to snuggle I'm starting to loose hope.
