What is the oldest, VERIFIABLE, queen you have? I am curious to hear how old your queens are...
For selection, time, is a great indicator. The more measurements that I can collect over time, the more accurate the measurements become as an indicator for future generations.
For example, I have a small percentage of queens that make it to their 5th spring, but I have not had any make it through that year. The old queens are kept in full size production colonies without any special attention. I want to see what these old girls can do!
Part of my interest in asking for your input stems from the "Drone Project" I did a couple of years back. I still have a couple of the queens that were inseminated using drones from all over the US. If they make it through another winter, I was thinking of repeating the project using drones from really old survivor queens. Any interest?
