I start free ranging broods at 3 weeks without hen. They are kept in coops until I get off work when they are allowed till dark under my supervision. Problem I have is when chicks go to their box they keep making all sorts of racket as they jostle for position in group. This racket is likely to attract predators that might otherwise not visit. Any thoughts on how to get chicks to settle in faster. Those attended by hen or on rare occasions broody rooster are much quiter.
