She is only 13 weeks old. I bought her from a hatchery at a day old. She was my favorite of that group of 6 and I held her a lot. I also hatched out 6 more chicks 3 weeks later and she is awful with them. She doesn't stop at a peck but actually bites them..hanging onto their neck skin. Today she did the same to one of her flock. She will sit on my lap and likes being petted but I am getting worried she will hurt the others. ALL suggestions are welcome.
