I have the Worlds Tiniest Swarm- and another very weak little colony that may be queenless. Both are in Nuc boxes and one has three frames with bees- the other just two. I am thinking of combining the two into one. One has a recently emerged queen that may or may not have mated by now- the other is possibly queenless.
If I wanted to merge them how might I go about it? The other option is to let the one with the young queen slowly build up- and give the other a frame of brood with eggs on it. I am not fussed if they build up slowly- but just want to make sure they both survive.
One has an upper entrance- so conceivably I could stack the two nuc boxes with a few sheets of newspaper (how many layers should I use?) in between and let the bees chew through until they combine. Once they have melded into one I could move the frames from upstairs down so that the bottom box is pretty much full and they can keep it warm and cozy.
EDIT: I just realized there is a complication- the two colonies are here at my house and they are a few meters apart. I would have to move one to the other- which might cause some confusion with foragers… perhaps i should just build them up individually…
