I put a frame with queen cells in a QC. 4 weeks later, there is a very large queen in there. Not a small virgin. A very big bodied queen, but not an egg, larva or capped brood anywhere. I first checked 3 weeks ago and found her right away. Now 3 weeks later, still not laying. They had eaten the honey on the frame so I added a frame of honey. There is lots of pollen on her brood frame but at least half the frame is empty, so lots of room to lay. The numbers in the nuc are starting to dwindle. Do I add a frame of brood and continue or cut my losses and combine with another hive.
