Hi, I noted that when my buff orpington ? hen or roo.( not sure yet) went to roost tonight he/she was shaking her head, would close one eye and I noted her comb would go pale. It would return to normal when when she stopped. She looked like something was really annoying her in her head. Almost a "paranoid look" on her face. She has been acting normal. Eating, drinking, running around, normal... I picked her/him up and he/she was less than impressed. She acted normal. Eyes clear, comb bright. After she went back up to roost she/ he seemed normal again. I have read some that lice or parasites can cause irritation in the birds. I am new at this. Any help would be appreciated.
