Can I keep 4 weeks old chicks with 2 months old chicks?

Hi, following this amazing website for all the info I need for chicken/quails.. and hopefully for turkeys soon!!
I have 9 of 6 weeks old chicks, and 14 of 4 weeks old chicks. I have a bigger coop that can have all of my chicks in one place. Is it okay to have these two different ages groups together?

It should be ok, as long as you allow for a good bit of integration. After integration, I currently have 11 week chicks with 3 year hens.

Though make sure the coop is big enough (list dimensions?) as integration takes extra space, and that the weather is ok.
