Yesterday one of my older girls was acting lethargic and was laying on the ground puffed up, I separated her from the flock. I gave her a warm bath that seemed to perk her up, when I examined her, her belly was red and hard. She also has some scabs on it. She has diarrhea as well. I don't know what to do for her and we don't have any vets in the area. She is still eating and drinking. Any advice would be greatly appreciated.
