Re: Threshold for spliting
I cannot say how well it will work just yet. I have attempted this method this past summer with some degree of success.
Next year during swarm season when I start finding queen cells in my hives. I am already set up with 12 queen castle compartments and 8 additional mini mating nucs. I don't think this will be nearly enough. Btu as i find queen cells that frame along with one frame of stores will be moved to the castles. Any additional cells on that frame will be removed and given to a mini nuc. Any cells remaining after all compartments are filled will be placed in an incubator to emerge. These will be sold as cells or virgin queens or used to replace queens that failed to survive their mating flight.
Significant Minority vs Insignificant Majority, 20% of causes produce 80% of the effects.
