After moving and dividing some hives several months ago, I finally got
around to checking through the brood chambers and found a number of Drone
laying hives. To two hives I added nucs with queens directly into the hives
with lots of smoke. One nuc was 2 frames and the other 3, and after 35 days
both hives were fine and I saw both queens.
To three hives I added one frame of brood with a queen cell and after 35
days two had nice young queens with sealed brood. The other had no queen or
brood and isn't worth trying to save.
