This didn't seem right to me so thought I'd seek advice. Our hens are now 9 months old and I noticed some rough feather patches on a couple of them and wasn't sure if it was early stages of molting or something else. Today I opened up the nest box and found one hen sitting there while another hen was pecking/plucking out the small feathers on the back of the neck of the nesting hen. The nesting hen being plucked just sat there seemingly undistrubed by the pecking. Is this just their way of helping each other with feathers that are hard to reach? or is this a bullying hen picking on her sister? Thanks for any advice!
