I have a chicken that is one year old. She is a sassy and fiery chicken with tons of personality but one day I noticed she was very lethargic. Since I no longer live at home, I'm not around to watch over my babies and was startled by the drastic change in temperament. The next day she was back to her old self again and was running around so I wasn't worried. When I came back next weekend, she was very slow again. We took her inside where we have a good size cage for when a chicken gets sick. She refuses to eat, but drinks a little bit every now and again. We have tried pedilyte, plain yogurt, oatmeal, softly cooked eggs as well as raw, everything and she won't eat. She is attentive, but weak, and only grows skinnier and weaker. We cant seem to figure out what is wrong with her, and are quite honestly surprised she is still alive. Her comb is normally colored, not losing any feathers, and otherwise has a completely normal appearance other than weight loss. We also know now that she doesn't lay eggs (4 chickens, 3 eggs daily and when she was brought inside we still got 3 eggs). Has anyone else encountered this before or have anything that can help?? None of my other chickens show any symptoms like that and are happy little fluffy butts.
