I think there lies the lesson.
Most Beekeepers are shown nothing about raising a new queen. Many Beekeepers only have a couple of colonies, these Beekeepers IMO are a majority and should if any one be raising new queens with walk away splits, anything to improve local stock and bring an element of sustainability to their Beekeeping but many Beekeepers dare I say are arrogant and Believe queens must be produced in the most difficult method they can think off when actually many Beekeepers would just be happy getting an extra nuc up and running each year. Just a thought.
