I Was looking at M Bush Pics of a "floor without a floor" and don't quite grasp the point of it????look like a simple removable floor (or top)
It is otherwise known as a "Cloake Board", named after Harry Cloake, the New Zealander who developed the principle. It is used for queen rearing. I explain the process here -> http://robo.bushkillfarms.com/beekeeping/queen-rearing/
Ahhh so its just a simpley to remove devider. You mention on that page useing teh hive with the queen trapped below as a finisher how do you keep the multiple queens from getting to each other, and yet let the nurse bees have access? I was thinking you moved tehm to an incubator when they are a day or so from hatching?? (assuming mine will be on a frame and not in a queen cup, so I don't think I can remove them without damage.
Yes, a finisher just completes and caps the queen cells. The cells are moved to individual mating nucs before they hatch.
Robo has the detail, but the concept is simple. You can set up a queenless portion of the hive for a cell starter on the top and turn it into a queenright cell finisher by simply pulling out the tray. The other advantage is you can manipulate having entrances on opposite sides to shift the population of bees around.
