So my 20 week old chickens have coccidiosis... I got in touch with an avian vet in the area to confirm it via fecal samples, and they have been on corid for 10 days... I got in touch with her after day 7 to tell her they were still symptomatic and she said to give it a few more days. They all seem fine and are eating, drinking and behaving normally but some are still having foamy yellow poops and mucousy bloody diarrhea. One rooster and one hen have started turning pale again (most of them were pale early on but started looking better about day 5). I called the avian vet again because it seems like the next step would be some kind of antibiotic? But instead she's leaving the office for a week and told me just to take them off corid and see how they do with some probiotics. I'm supposed to call if they get bad again and hope the office can get a hold of her. They've already been on probios this whole time... I'm worried that I may lose my hen and rooster if they're already getting sick again. Does this seem like good advice to you folks?
