Two brooders into one tractor?

[Booksnboys]

This is our second time doing meat chickens (Cornish X) & we started an experiment with two brooders - one with a traditional heat lamp & one with a plate style brooder heater. So far they are all looking great with the traditional heat lamp ones slightly bigger.
My question is in a couple weeks when they are ready to move outside into our tractor, will I have problems putting the two groups together?
My husband has a plan to put a divider down the center of the tractor if needed, but we didn't know what we should do.

I'm not familiar with Cornish x, but chick integration can sometimes have no issues and sometimes have quite of bit of tusseling. I would start by dividing with a fence that they can see each other through and see how they act towards each other.

How many chicks in each group?
If there's many and the ratio is fairly split, it will probably be fine to mix everyone together because it will be a neutral meeting ground and so many new birds that it's not as likely any will be singled out for bullying.
