Mixed ages chicken babies?

[AnKa]

I am getting 3 more babies tomorrow - like 3-day olds. My other 4 babies are between a week and 1 day and maybe almost 2 weeks. They're pretty big already!
So do I put them all together? Do I let the new ones settle in in their own brooder for a couple of days until I am sure they do well? I have all I need to set up a second brooder so that's not an issue. I just want them to all get along in the end.

You can put them together and watch them carefully to see how it goes. Be prepared to separate them if you need to. Since the oldest is two weeks you may be ok. Initially I would separate them. for a few days but put them so they can see each other.
