Re: Splitting advice: nucs vs mediums
I think you are correct. I have and use a bunch of nucs - including some that hold 3 half size medium frames - but I have also used full size singles (8 frame mediums) as mating nucs with only a couple of frames of resources, closed bottoms and reduced entrances - and I can't see any important differences in performance - during the main season, winter might be different.
I used to use a special made wooden divider board to make it more cozy, but then I realized that a frame of undrawn plastic foundation works just as well. So just put the bees on one end and fill it up with plastic foundation - that way it's no emergency if they decide to grow.
I do agree that in a lot of ways they do better in tight quarters, but larger hives are easier to manage and require less attention. That's why there are so many flavors.
