I have a yr old leghorn hen, who has been picked on by for the last month. we have put in a cage and got her healed up although she is still bald on her head. This one chicken seems to have it in for her. she won't fight back, she just cowers in a corner. She is eating and drinking and lays an egg every day. The problem is she sits on the roosts by herself most of the time. When I pick her up she immediately lowers her head on my arm and falls asleep, I can hear her breathe (I call it sleep breathing) and her head just kind of tilts slightly like she's really sleeping. I have dusted her and the others for mites. Is there something I can do to boost her energy? I am far away from the nearest tractor supply, so can I feed her something or use people vitamins? Should I separate her for awhile again? Please help,,,she's now my baby.
