I have a 2 year old hen who i thought was going broody as she is staying in the nesting box, When she does come out my other hens are pecking at her. I notices yesterday that she now has feathers missing around her head and it is very Scalley on her skin. I have checked the best i could for lice and didn't see anything at this point. What can i do to help her. Im worried they way the others are treating her that there is something wrong. She is eating and drinking when she does come out.
