introducing different-aged pullets into coop

[chick-flo-a]

I have 5 chicks in the brooder box - 2 of them are about 10 days older than the others. They are quite a bit bigger and seem more than ready to go into the coop. The bigger ones are almost 7 weeks old. I'm wondering if there will be any problems if I put those two into the coop this week and then introduce the other 3 into the coop in a week or 10 days.

If they're 7 weeks old, then the younger ones are nearly 6 weeks? They can all go out together then.
