Three of my 4 hives are overwintering very well, ones a NUC and they are all packed with bees. But one hive has a small cluster left - between 2 frames, they've gone through pretty much all of the candy board. I want to try to save them. Thinking of removing the bottom super (they are in a 2 deeps stack now, with QB and CB) and quickly making a replacement candy block today along with adding a winter patty to help them through. If it was in the 50s I suppose I could pull a frame from a strong hive but I really don't want to tear into the other hives and risk them, hope to see 45F today.
Any other thoughts on helping them out?
