I have never had much luck getting a laying worker hive to make a queen cell from a brood frame with eggs or introducing a new queen. You may have got lucky but time will tell. I hope it works out for you, i don't find it worth the time or effort any more, i now just dump all the bees out about 50ft. from where there hive was and take the hive home. Any worker bee that wants to work will find a new home and the drones are welcome in any hive they chose anyway. Jack
