Any help is appreciated. I got 3 new chicks a week ago. One guy had extreme lethargy and runny diarrhea and the other two have to gotten the diarrhea as well. I took them to our avian vet and he said coccidiosis and prescribed trimeth/sulpha suspension. Ive been giving it as directed along with a little squirt of yogurt each time to help with normal flora maintenance. They had a few cruddy days and then better, and better yet the next day. Now today, the guy seems frumpy again and they all still have some diarrhea mixed with normal poo. Does anyone have tips? We got excited when we saw that they were feeling better and let them run around for a bit. I wonder if that set them back?? Right now I have ACV in their water. Any other natural remedies that might get them back on track? I'm so worried.
