About 3 weeks ago, I installed a nuc in a 10-frame deep. There were several marginal weather days, so we had to move the nuc into the deep in one move (all frames together) without looking for the queen. At the same time, I did a newpaper combine onto the nuc with a medium from a hive that was busting at the seams. I thought it would give the nuc a nice boost while relieving pressure off the other colony. The combine seemed to go well, and activity around the outside of the hive looked good the last couple of weeks. Today, I opened things up and to my great disappointment I saw frames covered in capped drone brood. I couldn't see any worker brood. I either started this nuc with a drone-laying queen or a dead queen and subsequently laying workers. How can I tell the difference? In addition, now that I was able to separate the frames of the nuc, I found two of the 5 frames were bare foundation. Argh!. I didn't see any queen/emergency cells which leads me to believe the drone-laying queen idea. How should I handle this with the Ag center where I bought the nuc? Not sure if introducing a good queen will save the colony at this point. Can this hive be saved?
