My chicks are seven weeks old (eight weeks old Monday) and love to try and eat my hair. It all started back in the brooder days when I’d reach in there my hair would fall down and they’d peck at it. Now, when I go out in the run and sit down they enjoy eating my hair. They’ve started actually pulling it out. I have thick hair so a lot of the times I don’t even feel it. Should I stop them from doing this? Thanks!
