This fully assembled, four compartment queen rearing box provides a similar tool as our mini mating. However, since this accommodates full sized frames, it provides the option of putting in a frame that has a queen cell on
it to allow it to emerge. Then, after she has emerged and mated, you can take the frame with the mated queen and put it in any of your other hives that needs one. Each compartment allows two frames, but other numbers of frames can be used by removing the glass board dividers. It will need a migratory or telescoping lid. It is not included in the kit.
