My 2 new girls, who are 8-9 weeks old now, just came home last weekend. They seem very healthy, and have normal feces. I took a fecal sample to the vet and they are positive for coccidia. The vet recommended that I get, from the Co-op, either something called OTC or amprolium & sulfa. Is one better than the other? What does treatment entail? The girls are in quarantine from my other 2 chickens and will be until they have a clear fecal. Just looking for advice or suggestions! Also, should I be at all worried? It's not horribly difficult to clear up, is it? The girls came from a friend of mine who has a lot of chickens. She keeps them well--certainly not to my standards, but mine are pets. They are kept clean and her hubandry seems sound. Is it pretty 'normal' that they would have it? Thanks!
