I've got a 5.5 year old white leghorn that for the last month has been having diarrhea, and lethargy. She's old and had an array of issues (bumble food, mites, prolapse vent), but they were all treated and cleared up. I wormed her, added probiotics, put her on a round of amoxicillin, then baytril, and both times she perked up, seemed to get better and was eating and rooting around with the other birds, but her diarrhea never cleared up, and a few days after she stops the antibiotics, she becomes dumpy again. No blood in her poops, just very abnormal, watery, sticking all over her vent. Right now she's eating and drinking, but sitting a lot and not very stable on her feet. Are there any other antibiotics i can try? Put her back on baytril or amoxicillin? I don't have access to a poultry vet or any vet that will run a fecal for me. I assume she has some kind of internal infection, she was previously laying soft shelled eggs.
