On Saturday, my Barred Rock hen, Pepper, was very lethargic and did a lot of dozing off while standing up. She also had mucus in her poop and didn't have much appetite. I took her to an avian vet and they did a stool test and found cocci. Gave her a prescription of 1 TMS (Trimethorprim / Sulfadizaine) tablet per day (1/2 morning, 1/2 evening). She had 1/2 the first day and a full dose yesterday and now 1/2 this morning. My question is, should she be getting better by now? She is not as lethargic but still very quiet and not eating much. Her poops are still very liquid / mucus filled and some blood. Has anyone else treated cocci with this drug? I am wondering if side effects of the drug are making her feel lousy too. The vet said something like she wasn't 100% sure that cocci was what was causing all of her problems, so maybe she has something else going on as well? I have 2 other hens but they seem fine, normal poops and energy. They are not being treated but the vet gave me some sulfamethoxine powder to put in their water, but not until Pepper is done with her pills.
