Just a note..Several strains of coccidiosis, both old and new, have shown growing resistance to Corrid(amprolium). Also, Corrid is shown to be antagonistic, even toxic to thiamine in the rumen, so you probably want to consider a B-fortified pack. Most professionals in the small-ruminant field are now moving away from Corrid, so would always suggest you check with vet before application, even for OTC products...There are other brands available if you want to compare.
