Help! Mixing pullets!!!

[Chanticleer20]

Okay....our 20 chicks are about 5 to 6 weeks! They have been out in the coop for about a week!!! They are doing great!!...my Mother in-law...got a round of 20 chicks about a 2 weeks after us!!! Our babies are all about the same age! But her babies are mixed in age!!! There is about 4 chicks that have to be about my chicks age!! And they are ready to get out to a coop!! But!...we don’t really want to take the 4 out without the others...sooo I was wondering if we can take her older girls over with our girls! Are they still at an age where we can mix them!!?...they are at least 5 to 6 weeks!!!

What do you want the end result/ flocks to look like?

And how much space do you have?

I would think it would be easiest to keep the 2 groups as they are... as long as everyone is happy.
