Sam, I stick to treatments that are specifically sold for coccidiosis. I don't like taking chances with cocci. If you treat with Corid, the only thing I've found that you can add to it is Tylan. I would be cautious about adding anything else including ACV and garlic.
What I meant was that Tylan is compatible to give with Corid. But with all these meds, I would think twice about adding anything in with it like acv etc.
