It depends. They aren't usually as bad as chickens, but you can still see some problems especially from the hens. I tend to separate the young by a fence until they are about 3 months before I let them mingle.
You will have an interesting time moving them for sure. Last year's poults, when I moved them to a bigger brooder, they stood in a weird huddle in the corner for 2 nights before finally adjusting. I used to have a bourbon red hen who rubbed her snood off pacing the fence as a poult. They are quirky emotion birds.
