One of my barred girls has had a bald patch on her chest for a few months now. Originally thought it was a molt as there were feathers around the laying box and coop on and off. Today I noticed her spot is bright red. She is still acting and eating fine (though she's a little less fluffy than her coop-mates). We are entering a colder than usual spell here in NE Ohio and I'm wondering if there is anything I can/should do to help her. We are not heating the coop thus far this winter though I do have a red heat bulb if needed... Any advice/suggestions are welcome! Thank you!
