I recently got a total of 10 chicks and they are all finding their place. They seem to be establishing who is in charge. One of them appears to be too mean. She pecks all the others and seems to bully them. She will step on them and chase them. I thought maybe she was bored so I have included extra things for her to climb on and entertain herself with however it seems to only work for a few minutes. I am worried about injuries. Is this normal behavior? Should I separate? Any advice would be much appreciated!!! All my chicks range in age from about a week or so to maybe three weeks. She has rightfully earned the name Chyna!!
