I had a hive of NWC come out of out winter really strong with a very high population. The weather here in SW Pennsylvania has been very warm lately and continues to look that way. I was able to check my hives this weekend and saw the bees began building about 3-5 swarm cells (empty). I decided to split the colony that day for no other reason than I had the time to do it. I can't find any NWC queens out there in April. I can wait for the colony to raise one on their own, but would rather save the time buying one. Anyone know of any NWC queens available in April?
