I spent this weekend three nucs from two of my hives. I was doing it under the mentoring of a former commercial beekeeper (he had about 800 hives until the mites hit). Some of the frames we were working with had irregular drone comb on the bottom as well as cells that are drawn too deep (mostly the upper band of cells where honey is stored). When we went to mix the frames up and make the nucs the frames would not really fit together because of the drone comb and extra deep cells in places. He said it was not necessary to scrap off the drone comb and that if the frames were drawn too deep just to shove them together and the bees would take care of it. This has not been my experience because last year I shoved some frames together and the bees braced them all together. I have heard of bees tearing down cells if they were to deep but I'm not sure if this is true. Is it really ok to just shove the frames together and if not what do you do?
