Heritage turkey poults

I’m looking to add some heritage turkeys to our crew. With different availabilities on the kinds I’d like, some may be up to 9.5 weeks older than the others. Will this be difficult when it comes to integration? I’ve successfully integrated chickens with a similar age gap (and larger than) but I’m not familiar with turkeys and can’t find much info on it comparatively.

I’m also looking at ordering from Metzer and Cackle - any different suggestions? I’ve gotten most of my waterfowl from Metzer and was happy overall. All my chicks have come from localish hatcheries and haven’t had to be shipped. I’ve never ordered from Cackle. Located in Ohio.
