Getting chicks of mixed ages?

[Curlita]

If I get 2 chicks younger than 3 weeks and two chicks who are between 3 weeks and 2 months, will the older ones beat up on the younger?

Maybe that's a stupid question, but I'm a first time chicken owner and I don't mind looking a little stupid.

I'm going to look at chicks on Monday and I know the guy has one of the breeds I want in both age ranges, but only the older chicks in the other breed.

I have chics that my broodys have been hatching since April 1st they range from about 7 weeks all the way down to a couple days old, everyone gets along fine, when i add a new baby they will find an older chic and nestle under there wings for a couple days until they are use to everyone, i have a total of 8 together right now expecting 4 more anytime, i have old english bantams, Slw mixed with Frizzle and a couple of mutts so they are mixed standard and bantam ... Good Luck
