Hope the Sulmet does the trick. Just wanted to add, I had a pullet with cocci last year and treated everyone. I was freaking out because I kept finding blood in their poop even after treatment. Everyone seemed fine, I couldn't figure out why the bloody poop. It turns out it was just intestinal lining from the medicine being so hard on them. It was firm poop with bloody strings in it. I just wanted to pass that along in case it happened to you. Keep us posted on their progress. Sounds like you are doing a good job, it's amazing how they can pull through with the right care.
