Three queen hive

[bee-nuts]

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.

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