I have a 2 yr old RIR hen that has been sitting around shaking her head. She's not really lathargic but won't come out of the coop. She is not gagging and is breathing fine. I thought maybe something was on her head but can't see anything and she doesn't shake her head like that.(It is just a feeling I have) I think something is in her head or ears. She looks healthy except for that. Any suggestions?
