Just noticed my 10 month old speckled Sussex isn’t feeling well. She is pale and all puffed up and not wanting to interact with me or the other chickens. She will eat when I offer her a treat. We are in north GA, it is about 30 degrees at night and 50s during the day. Can’t find an obvious reason for her to be sick. Most of the girls have slowed way down on laying, but I have no idea who is still laying. I will add poultry cell to their water, any other suggestions?
