Oh shoot. I just saw another thread about this. so sorry!
I have some 2 weeks apart together right now. i haven't had a problem. 3 weeks is a bigger jump, so watch them, but they should be fine. As far as heat goes, put the light (I assume you are using a heat lamp?) On 1 end or in 1 corner of the brooder so they can choose the amount of heat they want and get away from it when they need to. That part isn't a big deal.
While I have never had a problem with trampling, other people do, so watch them carefully for a while. Some people say chicks as many as 4 weeks apart can share a brooder with no problem.
just watch out for pecking, trampling, and make sure the bigger babies can get away from the heat when they need to, and you should be fine.
A little pecking is totally normal. It is to a chicken the way butt sniffing is to a dog. just make sure it's done out of curiosity, not meanness. Good luck. :)
