I have 10 10 week old chicks that have been eating medicated starter grower. Recently I started throwing cracked corn on the ground for them and let them free range now that I have the coop finished. Theyh are under trees and in a pretty dog proof fence and so far no troubles. If they run out of food for a a day or 2 will the free ranging be good nutrition for them? I know they will miss the meds, I'm just curious.
