Wow. That is impressive. You need to graft some queens from her. I have a couple of yellow-dots from last year, but I think they were both late season (2017) queens. 18 months seems to be all that I can keep a queen viable.I’ve been working in the bees all day today. A pleasant surprise….a queen with a white mark. 2016 vintage, vsh from Johnny Thompson at Broke T Apiaries.
Starting her fourth year. Plenty of brood....good pattern.
