I have a customer that is buying 2 of my over-wintered nucs next Spring and he would like me to mark the queens. I have seen some youtube vids where beeks just pick up the queen with their fingers and mark them. Won't they sting you? I think I'll wait until Spring this way if I kill them I can raise new ones. Any other methods or tricks from the pros'? My wife got me the pens from Brushy; $$$! for some Sharpie's along with a tube and plunger looking device to try it with.
