I have medium frames in my deep boxes right now. I eventually want to switch to all mediums. Most of the time, the bees build drone comb below the frame and it can easily cut off and then move the frame into the medium box. If it is worker brood when I move them, I can cut it off and put it in a medium frame.
Yeah Jim that's where I'm going with this. I plan to turn my deep boxes int multiple chamber mating nucs. Gonna use yje old deep frames for traps per Bailey's suggestion.
