Is it better to overwinter in a five frame nuc that is build upwards or a full ten frame hive. Do the bees keep warmer in a skinny tall hive or fat short hive?
I overwinter 10 frame single deeps, 4 frame single deep nucs, 4 frame over 4 frame deep nucs. The 10s do well, the 4 singles require a lot of attention, the 4 over 4 do the best. To much moisture and not enough stores is the main concern. I believe the 4 over 4s do best because they have stores overhead and don't have to make the side jump like the 10s do.
