About 1 week ago I noticed a lack of eggs in one of my hives and following some advice from Mr. Bush, I tossed in a frame of eggs from another hive. A few days later I repeated with another frame because I hadn't noticed activity on the first frame. Now I've got about 15 queen cells on the 2 frames. I'd like to salvage at least a few of these queen cells for another nuc, etc. I'd cut them out but they are on PF-120 plastic frames. Does anyone have a suggestion on how to best save some queens?
