Well, cold weather starts about mid Oct here. I have no experience trying to overwinter nucs. I have a few nucs that were started in early July. Most of them have built up to 10 frames and will be overwintered in a single deep. However, some of them have not made it past six frames. Would you take a frame of honey away and overwinter in a five frame nuc box, or try to build them up in the remaining four weeks? I could also combine to fill the deeps. I have a basement that stays at about 45-55 degrees in the winter, and I could screen them in and overwinter in the basement. The problem with that is that I would have to take them outside once in a while to let them use the potty.
