Greg: You have a major problem, and it is NOT swarming. Are you sure the cells of the face of the comb are emergency cells rather than drone cells? When a hive becomes queenless (as yours is), the bees will usually pick just one or maybe 2 larvae to convert to queens in Emergency Cells on the comb face. However, if you had a laying worker, she would scatter eggs around rather than in a pattern, and of course these unfertilized eggs can only develop into drones. You installed these bees on 4/18 which is 17 days ago. Almost half of your purchased bees are already dead; and the rest will all be dead in about 3-4 weeks. Even if you got a new queen tomorrow, I doubt that there will be enough bees to nurse the queen's new brood. This group of bees is not worth saving, better to start over with all new fresh stock. You did not mention any sugar syrup. Are you feeding 1:1 syrup? Too many beekeepers fail to give bees a good start by feeding them continuously for 2-3 months. This is the best I can say with the meager information you wrote. Good Luck! George
