I fed my bees early this spring with sugar boards. We had a terrible nectar season last year, then a long cold winter. Well, then we had a bunch of trees all started blooming at once. The bees went nuts. I probably had 50 swarm cells in 6 hives. I had given them room and everything, but they were recognizing abundance.
I now have 35 nucs. (I didn't cut any of the swarm cells. If there were 3 on a frame, I just the frame in the queen castle mating box, or in a nuc.)
We're having 3 days of rain, the beginning of which most of these capped cells will open up. So, at the end of those 3 days, all those virgin queens will be itching to get out.
Why worry its all beyond your control. Just let them do their thing. Then manage any nuc that doesn't have a laying queen in a few weeks. By combining with a queenright nuc. If you end up with more than you want or can handle, sell them. Lots of people still want or need bees. I hope you have a 100% mating success. Mine is usually 75-80% but one has to have a dream.
