I'm getting a batch of 15 chicks in a few weeks and plan to raise them free range (I live on 10 acres and have lots of room!). My goal is to raise them as naturally and organically as possible - meaning, I hope to feed them as little commercial food and medications as possible, especially once they are full grown and have access to pasture and can forage. I know until they're bigger that I'm probably going to end up using an organic brand of chick starter feed, but is it ok to supplement that with veggies and maybe very finely ground beef for protein? Has anyone ever raised chickens without using commercial feed, and if so what did you use instead?
