I have 25, 5 week ol chicks. I put them in their new coop 3 days ago. The first night I went out to check on them before I went to bed. I found two of my smallest babies all bloody. The one little chick is definetely a roo, He was in the worst shape. His back and chest were raw from being pecked I assume. The other little chick's chest was raw and bloody. I removed them and brought them into the house. They are both doing fine now, should I put them back in with the other chicks soon? Are there any steps I can take to stop this behavior?? I feel so bad for these two little babies.
