She holds her tail up. She tends to cry out if you move her the wrong way. I soaked her bottom in Epsom salt and warm water. She likes that. She is laying on her side in a quiet place. There aren’t many chicken vets around and one of them charges $100 just to walk through the door. She has the penguin look.At that age, it might be that she has internal laying, salpingitis, or ascites (water belly.) Is her tail held down or up? Can you see a vet? I would try to get her eating some moist chicken feed, egg, or tuna. If ahe seems to be suffering, it might be good to consider putting her down.
