I am not a fan of medicated feed eith but you gotta do what you gotta do to keep your birds healthy. I have read that the only "medication" that is in medicated starter/grower is the same as in Corid which iis just a thiamin blocker. The parasite has to have thiamin to live and Corid and the medicated feed blocks the thiamin.
Most feeds have just amprolium, but not all:

That one has bacitracin, it's supposed to help prevent NE.
