Yup, cocci for sure then. Good news is you caught it in time if they're not even acting lethargic. 5-7 days of treatment should do it. Dawg53 has the dosages posted somewhere too. I've used the Corid powder- clears it up fast. As long as you don't see any symptoms past 7 days, I wouldn't even do a followup treatment. Corid can be hard on their symptoms, as it blocks vitamin absorbtion. (It basically starves the cocci by blocking vitamin absorbtion, but too much of that obviously isn't good. More isn't better.)
