On 31st May I found sealed queen cells in a hive I had thought had already superseded som while before. I nuced the queen and went back on the 6th and removed "all" the emergency queen cells and found the selected queen cell in the act of emerging. I was expecting to just leave them to it for a few weeks.
Today (11th) I witnessed a swarm issue from the hive and pitch conveniently about 12m away.
While they were getting settled I went through the hive and of course found another sealed QC, though I also found a couple of very small open ones and one very long open one (looked nearly 5cm!). Also the emerged cell.
Not wanting to increase colony numbers and wanting to maintain a big colony for the imminent flow I destroyed all the QCs, collected the swarm and dumped it back into the hive.
Hopefully this will sort them but the timelines for today's few open cells seem very strange.
Any bright ideas what's going on? Were the open cells from the last eggs laid on the 31st? Seems a long while ago to have any open cells!
No other brood seen except a bit of capped sealed brood mainly drone.
Edit: maybe there have been a few laying workers & they have tried to make cells from their drone larvae, it would explain the extra-long cell too.
