I have two questions for the bee-line. 1. Does anyone have any knowledge of any study pertaining to bees that use water from a waste treatment facility? Would any heavy metals be possibly transferred to the hive or the honey? 2. Does anyone have any plans or specifications for queen mating nucs? How many frames, size, maximum number in an apiary, number of drone colonies to make sure of good queen mating?
