I've heard all different kinds of ages to let standard size chickens out to free range, but what age do YOU let your bantams out to free range? I have two eight week olds and they seem fine. The older hen (yes, I only have one. Predators ) totally ignores them. I didn't attempt to leave them in the coop all night with her, because it's been too cold for them at night. But tonight will be warmer. They're both roos (I'm getting rid of one soon and getting another hen) if that matters. They don't crow yet. So even though that jumped all around: 1.)What age do you let your bantams free range? 2.)Would you leave your 8 week old bantams in with a full-grown hen overnight? They have a sectioned off part they can escape to if she's being mean.
