Welcome to BYC. What are her poops like? I would get Corid and treat for possible coccidiosis. Dosage is 2 tsp (10 ml) of the liquid Corid, or 1.5 tsp of the Corid Powder per gallon of water for 5-7 days. You also can give 0.1 ml orally of undiluted Corid twice a day to give a jumpstart. An injury could also be likely.
