Why would ANYONE want to split a healthy swarm?! It's madness! IMO it should never be done, but I have a dilemma... I have a dying colony I call Kawa Bees, apis mellifera western bees, with 4 queen cells and a very healthy Japanese bee swarm of apis cerana japonica, a subspecies of honeybee native ONLY to Japan. I call these the Okera Bees. I want to try to save one of the Kawa queens and create a hybrid bee that is resistant to mites and a good honey producer... so I am splitting the Okera hive and adding a frame with the 2 queen cells to the split without the Okera queen. Here is the video
