30-40% here and still some touch-and-go colonies. OSR just colouring up, dandelions & willow out in force. White/yellow queens heading the survivors, of which two thirds are tiny brood areas and one third are bursting double commercial deeps. One or two terminal cases of PMS, some clearly DLQ, mostly isolation starvation of tennis ball sized clusters amongst plentiful stores - oh and mice (rats?) that have chewed their way in despite reduced entrances and good condition floors.
I'm scratching my head trying to work out what was different for the survivors. Preparations for winter, varroa treatments/timings, hive configuration, etc. all pretty standard, certainly by apiary, and yet some are thriving amongst the misery. I'll raise queens from those - this year I shall mostly be making bees.
