So I opened up one of my big hives to do a split before they swarmed and I was too late. I didn't realize they had swarmed until I saw a queen running across a brood frame with another queen on her back stinging her. I didn't know what to think until I found two empty swarm cells along with three cells on another frame completely capped. Both queens were in bad shape. One was limping and the other was very lethargic. So I pinched both of them, moved the frame with the swarm cells to a nuc then re-queened the original hive. I also took a box off with brood and honey and introduce a queen to that one. What a shock to see that for the first time.
