Re: Problem - two queenless hives, what to do?
While the "expert" requirement disqualifies me, and I keep bees in Langstroth hives, I would shake out the remnant, forcing them into the other hives. The remaining drone brood, depending on whether I thought they carried "good" genetics or "bad", and whether I felt I needed the drones to mate with my future virgins, I would either transfer them to another hive, or dispatch them and attempt to store the combs until another hive could use them. ( using the 80% coverage rule of thumb)
The Queenless swarm, I would either donate them eggs, or a queen cell from one of the "sweet tempered" hives. donating eggs risks less if you ultimately lose the whole colony, but if they do have a queen, the Queen cell would be lost, & possibly the hive that donated it. ( due to making it because they needed it). donating a capped queen cell , if accepted , will reduce the number of days before the colony is brooding, etc. If the queenless swarm does not have a queen, they can make one from the "sweet tempered" genetics of the donor hive (eggs)
The hive that is making queen cells, is it large enough to split?
with the relative hazards of queen mating, when a hive makes multiple cells, I usually try to split some out into mating nucs, to increase my chances of having a better rate of return.
I can recombine later, assuming I get a mated queen back.
While I was typing the above, I see others have also replied, with good thoughts.
Regarding the existing queen in TB2 ( the one making queen cells) I would consider splitting her out with enough bees , stores & brood to start a nuc, if she is not already gone.
My advice to split in advance of swarming draws me a lot of criticism, so it may not be that good of advice, but it is what I usually do. Good Luck CE
