Coccidiosis could be a problem if she is new to the soil. How is she acting. Signs of cocci are lethargy, standing around puffed up or hunched, diarrhea or blood in stools, ruffled feathers, weakness, and poor appetite. Treatment for that is Corid or amprollium from the cattle section of feed stores. Worms also could be a problem. Valbazen or fenbendazole are good wormers.
