Re: Something needs to change - looking for suggestions
It's simply a 5 frame box, stacked on another 5 frame box, ie, just the same as a normal 2 box hive but the boxes only have 5 frames.
I wouldn't mess with this configuration myself, but the theory of it is so the bee cluster can move upwards into honey stores through winter, rather than sideways which they do not prefer to do.
However an equivalent hive of one 10 frame box, is not going to require extensive sideways movement for the cluster so there is really not much in it, but the idea is there.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
