Correct, no other water, fresh each day and make sure they are drinking it. If not, then dip their beak into the water. Come back in an hour and do it again. repeat until the chick is drinking.I have 2 thermometers, on the babies side it's 80 and the older chicks is 75. I'll start the Corid, no other water right?
If they have an Coccidiosis overload, they look better by the next day usually. Keep following the treatments though
