3 frame nucs

[Sutty]

Just musing for next year.
Has anyone used these 3 frame nucs on top of another colony (for warmth) either as standard nucs, or as mating nucs?

easy enough to convert a standard brood box with moveable dividers to 2x2 & 2x3, or 2x5 nucs. Add varroa mesh on bottom of nuc brood box to use above another colony for warmth
