I had a strong hive. They made some swarm queen cells. When one got capped I moved the queen to nuc. My first cell should have had the new queen emerge Monday or Tuesday so I can only assume the new virgin queen took off with a bunch of my bees. I think I have some other queen cells and I put fresh eggs in there about 5 days ago. I can put more but I'm disappointed they still swarmed.
I had the same situation (queen cells) and decided to take them out and make a nuc / split with the frame containing the cells. This is now my strongest hive! I considered moving the queen and letting the virgin queen take over the existing hive. Now, after reading you plight, I'm happy I did it the way I did.
The thing I love about beekeeping is that every experience leads me to more knowledge that I can invariably apply to a later situation.
Hang in there!
