Good thing about Corid is that it won't hurt them at all if it's not coccidiosis.I haven't checked for any more red poop, but I am going to be getting some corid to put in their water later today and hopefully that helps. And we do not buy any red cabbage , pomegranate, beets or anything and nothing that my mom would have given them that they haven't had before. If I find another pile later I might put it in water to see if it really it blood.
