This is an easy to understand explanation of the Cloake board method. Makes good sense.
In considering the method I was wondering though if instead of introducing grafts, the beekeeeper instead let the bees select queen cells, what would be the down side.
The procedure would be
Place cloak board and reverse bottom queen right hive.
A couple days later move am frame of brood and eggs up and close the cloake board.
Five days later, inspect for queen cells. Open the cloake board if Q cells are present.
About 10 days after moving the brood and eggs, moventhe queen cells to MUDs and let the Qs hatch.
Am I missing something fundamental here? This seems much less invasive, by skipping the grafting step.
