Just know that they can still get cocci while on medicated feed, especially if raised in a brooder with no soil exposure for 4-6 weeks, then put outside. Medicated feed aids in immunity building, but does not necessarily prevent coccidiosis. It's easily treatable, though, if you notice the signs and get Corid for the 5 day treatment (Corid is concentrated Amprolium, a thiamine blocker)
