I had a hive that made swarm cells earlier this spring and they were mostly on
two frames (about a half dozen on each frame) with one or two on other frames.
I cut out the one or two "strays" and took the other two frames and put one in
each of two nucs with another comb or two.  I meant to go back and cut out all
but one or two cells in each nuc but I didn't make it, so they all emerged
(I assume) and a couple of weeks later I found a mated laying queen (beauties)
in each nuc.  I had placed these nucs next to a large hive with lots of drones.
I left the old queen in the old hive (moved to a new location) but I think they
still swarmed later anyway.  But I consider my nucs to be an unqualified
success.
