Shrinking a struggling colony into a 5-frame nuc for winter — anyone run double nucs over a strong colony?
Fifth year, Małopolskie. I have a colony that's queenright and healthy but just small — maybe four frames of bees after a poor season, not combine material in my view because the queen is young and from my best mother. I'd rather winter her small than merge her away.
Plan: shake them down into a 5-frame nuc on the frames they can actually cover — brood in the middle, heaviest stores either side — feed hard now, then winter the nuc ON TOP of my strongest production hive, separated by a solid board, entrance facing the other way. The idea being the strong colony below heats the nuc's floor all winter. I've also seen the divided-box version where two nucs share one box over a strong hive and warm each other through the partition.
Anyone actually run these stacked setups through a proper continental winter? Mistakes to avoid? My worry is spring drift and confusing the two entrances.
This is standard practice in a lot of German operations and it works well — a nuc over a strong colony winters better than the same nuc on its own stand, the floor warmth is real. Three rules from long use: the divider board must be truly solid and propolis-tight (shared air = shared robbing and disease routes), the nuc still needs its own full stores because warmth is not food, and point that upper entrance backward exactly as you plan, or returning spring foragers will drift down into the big hive and bleed your nuc dry.

I run the divided-box two-nucs version in Flanders every winter — two queens over one strong hive, partition down the middle. Wonderful system for keeping spare queens from good mothers, which is exactly your situation. Paint the two entrance faces different colours; it measurably cuts the drift confusion you're worried about. And take them off their perch EARLY in spring, they build fast up there.

Both very helpful, thanks. Solid board it is — I was half-tempted by mesh 'for shared warmth' and BuckfastLinda's robbing-route point kills that idea. Shakedown and feeding starts this weekend, entrance painted blue and facing the forest.
