Queen comparison
« on: October 03, 2017, 10:49:16 am »
Hey folks,
I remember hearing a presentation somewhere on the net a while back, where they compared queen vitality from years ago with commercially produced queens today. Can't remember if it was a presentation by Keith Delaplane, or what. Does anybody know where I can find such a presentation? Help, please!!!!
