Last spring we purchased two nucs and I thought they did well, but apparently I was wrong. Each hive setup was the same, I had two 10" deeps on the bottom and a medium above it. They went into winter with the middle 10" deep full of honey plus a little in the medium above it. I'm not sure what there was in the bottom 10" deep. During the summer they built comb between the frames of the two deeps so I couldn't separate the two deeps. I was concerned about doing more harm than good, so I left it alone. I think that was a mistake. I should have kept them separated and clean. After seeing no bees flying during a recent 70 degree warmup, I went exploring. All of the bees were in the bottom deep and dead. There was a little honey left in the outside frames, but not much. The honey in the deep above it is untouched. I assume they died during a cold spell, before they could move up? My next question has to do with cleaning up the hive in preparation for the packages of bees I have coming in May. They are easier for me to source, that's why I went the package route this year. The middle deep is full of honey. Should I move some of it down to the lower deep for the new bees to eat while getting established? How many frames? Do I leave the remaining frames of honey or do I harvest it? Thanks in advance.
