So I have broiler chicks arriving tomorrow. We are not a 100% organic family but we try our best to be as chemically and hormone free as possible. A friend of mine says when she fed Non medicated feed to her broilers she lost more then half the chicks and when she ordered some again in the fall and fed medicated feed, she lost none. Do you feed your broilers medicated feed for the first 3 weeks? How long does the medication stay in their system? What exactly is the medication in the feed? What should I do?
