I got my chicks on Tuesday and they have grown so much already!! I'm addicted. I'm already counting the days til my local feed store gets their chicks in... hehehehe My question is, when do I need to start offering grit to them? Is it in the chick starter? Also, can they start having tiny bits of treats now? I offered them a small bit of crumbled cheddar cheese last night and they attacked it! lol And, I know it's too early now, but when do I change them over to layer/adult food? Thanks!
