Hoping that someone can give me a good idea of what to do. 3 year old blue cochin hen is lethargic, not really eating well (but some), spends most of the time sitting in a corner. Her vent area is a bit messy, and her comb is a much darker red than usual (it seems). I did a fecal yesterday (work at a clinic-the vet knows nothing about birds) and found nothing. I am treating her with fenbendazole (Panacur) anyway. It should not be an egg issue because she was spayed. Any thoughts or ideas? I thought about giving her SMZ-TMP for coccidia but am unsure about giving both drugs at once. Thanks in advance.
