Well my plans didn't go quite as I wanted!!
I was just getting ready to inspect when the hive that had had more QCs swarmed. They are currently in a new hive in the (empty) neighbour's garden, I'll move them this evening to final position. Looking through it I found a lovely sealed QC, I guess I missed a charged cup with 3 day old larva
The other hive I looked through, found open QCs, reduced to one. Despite looking through 3 times I couldn't find her majesty. I then tried the "shake/brush and smoke the through a QE (I've only resorted to this once a VERY long time ago). Still couldn't spot her! Repeated, but with the now beeless frames in the bottom box. Still no joy!
(In retrospect probably hiding in bee-space under the edge of the box above the QE). Giving up and shaking remaining bees in without QE I then spotted her slip down between the frames!!! It was the expected mayhem by now so unsurprisingly couldn't find her even now.
Knowing they are queenright I removed the one QC I'd left, and will give it another try in a few days
just hope I haven't missed any more!!
