But three years same queen?
Yes, she was an exceptional queen, compared to most other "Amms" I and others have tried. Most struggled to full a single brood box. I had planned on replacing her this autumn but as she was still going strong will probably replace her next spring.
Whilst the numbers of Amm's I and other colleagues have used is not enormous our conclusions on them are pretty consistent.
