Let me start out by saying we are new to chicken owning. We have six 4 wk old chicks. Yesterday & today we put them in their run for a little out door time during the day. Today when we went out to bring them back into their brooder (the spare bathroom) we saw that all 6 of them have scratched their combs. We can only assume it was due to pecking @ things through the half inch hardware cloth. We have taken care of their poor little noses but is this normal?
