Just because a feed store does not sell it doesn't mean that it's not available.Chris, I've never seen medicated feed at my feed stores that contains anything other than Amprolium. Buyer beware. Read your labels. I'll stick to natural means, enhance my flock's immune systems, and allow them to develop immunity to the organisms in my own soil in the time frame that they were intended to do so. There is no right or wrong way to raise chicks: Medicated feed vs. non-medicated. Just make an informed decision which is right for your situation and your comfort level.
As far as feeding a Medicated or Non-Medicated feed,, I feed a Non-Medicated feed BUT I treat for coccidiocide in there drinking water. I have found that in my area chicks/birds do much better when treated for coccidicide since chickens never really grow a immunity to a organism/ parasite that is feeding off them.
