OK, Im thinking of doing something crazy. A three queen hive for basically a publicity stunt on you tube. Im thinking the two swarms I caught and whats left in the original hive with a deep and a medium for each brood chamber, a shallow in between brood with excluder on each side shallows. This will get extremely tall. Is there another way to keep queens separate without the added boxes in between? I want to get this ready for the blackberry flow.
Yeah, I know, Im nuts!
I would look more towards a side-by-side arrangement with shared supering.

As an example, I was going to do it this way:

If you really want it all in one stack, you can go with double-screen boards or doubled QEs.
