Re: Swarm/Supercedure Cells from a Bees Perspective
Swarming and superseding are two distinctly different processes. Ih hive one, it sounds like you have a swarm cell due to its location. Typically, there are more than one cells in the colony. Is it possible that you have a supersedure cell? If so, they don't like their old queen. If you pull the cell, you might make the donor hive queenless. If you're willing to risk it, go ahead. You're right, you can always combine. Keep in mind that if it is a supersedure cell and if your hive is queenright, they still won't like the queen so keep an eye on things.
The second hive may have swarmed but you mention supersedure cells. If those are truly supersedure cells, I might suggest that the hive hasn't swarmed but instead, that you are queenless or that the queen is failing....hence their desire to make a new queen. Yes, the first queen to emerge will knock off her sisters.
Now for after swarms. Swarming is complex, just like bees. The colony has a "group" mind that decides how to act. So long as the swarming desire is there and there are available queens to swarm with, they will do so. It's hard enough to stop swarming, much less stop after swarming once they get going.
I would check you colonies again and decide if what you're seeing is supersedure or swarming.....or maybe both.
