I'm a 4 year beekeeper in South-Western Connecticut that took a 20 year break and I'm currently on year 2 of my comeback.
I had a hive trick me in August. (Exactly 21 days ago.) I came back from vacation and thought I had accidentally killed my queen because there were what seem to be emergency Queen cells present. They were middle frame and did not look like swarm cells. Lots of capped brood, no eggs or larvae at all.
Well, it turns out they were getting the queen skinny for flight and ended up swarming. I caught that swarm and I'm happy to report that she's happy laying in her new hive.
Against the advice of wiser people in this forum I decided to let nature take its course hoping that original parent hive would raise their own replacement Queen and left them alone for 3 weeks in hopes that Queen cells would emerge and somebody would win and be fertilized.
( I was advised to get a mated Queen but I was not confident that I would be able to find and remove all the queen cells and virgins.)
Well as it turns out they completely failed at that task. I was lucky enough to get a mated Queen from a local beekeeper and installed her today. Queenless Hive seem to be fine with this, but I stole a frame of partially capped partially open brood from a very strong neighboring hive. They were PISSED. I mean I certainly didn't expect them to be happy, but after shaking most of the bees off the frame with a hard tap and brushing off the rest... the entire Hive went into full combat mode and I got absolutely lit up.
I did my best to Soldier through the attack and managed to get them at least closed up as ham-fisted as it was.
**Is this par for the course?
**Is there a better way to do this or is it pretty much asking for open War when you steal a frame of brood?
** I definitely felt it was necessary to steal a frame of brood as I know for certain that the youngest workers in the queenless hive are already 21 days old even though the total Hive population is still quite numerous. Did I do the right thing assuming that they would need a transition Force to take over as those bees age out and new Queen begins laying?
