I got a new hygenic queen from a local guy who's doing a little queen rearing. I supplied the 5-frame nuc to house her while she mated in his yard and the breeder made sure all was well before I took her home. It's been here for nine days. I thought I'd try and bring this nuc through the winter, but since it had a late start, not all the frames were full, and there was a lot of drone brood, I added a frame of worker brood with nure bees about 5 or 6 days ago. Toady I saw a supercedure cell that is not empty. Its on the new frame I put in last week. Other than that surprise, she seems to be laying well and there is a bunch of capped worker brood and much less drone brood. They are putting up pollen and nectar, Any thoughts on what to expect or what I can do? Is swarming/supercedure unavoidable?
