I had a very busy hive that lost it's queen a month ago and I let them build queen cells to replace her. There were two frames with queen cells and I made a nuc from one of them. The nuc has a virgin queen. Easy to find in a nuc. I inspected the busy hive very carefully and was not able to find any virgin queen. Too many bees and easy to miss her. She might be in there? If she is in there she should be laying in a week or so. So my concern is that if I wait too long to find out that I might have a laying worker problem. If I introduce a new queen and she is in there, than problems!! What to do?
