Had that same issue last year. A split I made because there were queen cells and they were gonna swarm. I moved the queen, brood and alot of food to a new location, bad weather, emerging queen inability to get out to mate -- the outcome, laying workers, it devastated one of my strongest colonies. Remember that picture I posted about the laying workers? I noticed too late to do anything good with the colony. It was a sad thing because this colony had been around for many years. Beautiful day in this great life, health. Cindi
