When rearing queens using the queen-right method (Ben Harden method) you add the frame of cells in the top brood box; seal the top box from the bottom box with the queen for a day; and then open them and wait for the cells to be capped. Now, with all those growing or sealed queen cells in the top box, wouldn't the colony be induced to think it's time to swarm? I don't want to lose my precious queen.
