My vet informed me that my barred rock has coccidosis and intestinal parasite. She deals mostly with dogs/cats, but is the only vet around that will look at chickens. She said it was up to me wether or not I wanted to medicate, but that since its an adult, it most likely will not kill the chicken. I ve read differing opinions on what to do. I was wondering if anyone has experience with this, and what should I do? Thank you
