Being in a hurry and a bit short on equipment at the moment, I recently hived a sizeable 'queenright' swarm in a deep over an excluder on top of an existing colony that was in a single deep.  Only the original hive entrance was left to both colonies' use.  The swarm was collected over 30 miles from my apiary.

Since then, I've noticed that just about half of the swarm bees have drifted to the adjacent hives in the apiary.  This brings me to a question about 2-queen hives: when bees from the upper colony leave the 2-queen hive for a flight and, up return, smell the workers/queen scent from the lower colony, do they get confused and look for another hive to enter?

By the way, both queens in the dual hive are laying well.
