I caught a 7lb swarm on May 12th (roughly 6 weeks ago) and it's building very quickly. I recently observed eggs in some queen cells hanging from the bottom of frames (foundationless) in the brood chamber, and today checked and there are roughly 5-7 with larvae floating inside. The hive is queen-right for sure and there is plenty of space for brood expansion and in the super.
Is there a way to know if these are supercedure or swarm cells? I thought supercedures were in the middle of the frames, though I know it's fairly common for a primary swarm to supercede the old queen. These queen cells are on the bottoms, so I'm thinking they're swarm cells. Is it possible for a caught-swarm to build up and swarm again 6 weeks later? I don't want to lose these bees to swarming! (Though I do have a bait hive up...)
What do you recommend doing?
I'm thinking I'll make up a 2-frame nuc with the current queen and cut out the swarm cells when they're capped and make up more 2-frame nucs (leaving 2-3 queen cells in the original hive with the majority of the original resources)
Coincidentally I grafted for the first time 2 days ago using the Ben Harden method (in a queenright cell starter/finisher) and got 14 out of 21 to take. Not sure I'll have enough resources for that many 2-frame nucs, but I'll give it a go! Primarily I'm looking for suggestions on how to best deal with the swarm cells that spontaneously appeared. Thanks!
