I currently have two commercial hives stocked from two 5 frame national nucs. I've padded out the edges of the national frames so brace comb isn't a big problem.
My plan is once the commercial frames are drawn out to add a national box as a super above the queen excluder and put the national combs (minus queen) into that and add 5 undrawn commercial frames to their place in the brood box. My thinking is the brood in them will hatch and leave the comb the national frames but no more eggs will be laid in it.
Obviously this will be pretty disruptive to the bees with the queen suddenly finding her brood box going from 11 drawn frames to 5.
Was wondering what do people think of this approach? Is there a better way?
