For those who are using just medium boxes, are your nucs medium also?
Yes.
Is this the configuration you use... 2 medium boxes?

Works like a charm. But at those prices I suggest making your own or buying deeps from Mann Lake Ltd and cutting them down. You'd be surprised what uses you can put the left over 3 inch to.

I buy some from Brushy Mt, but I just buy the boxes and make my own bottoms and tops. I make a migratory top. Actually I make a top with a top entrance. I also make four, three and two frame nucs. An eight frame box (my standard box for my hives) is exactly the same size as a five frame deep nuc.
