>I hand graft my queens but am wondering if anyone ever experience the 2 larvae grafting, leaving the nurse bees the option of 2 larvae?
When I was doing the Jenter method I sometimes had two larvae in a cup. I would say it probably makes no difference, but then it's likely that the food is getting shared by two larvae so they are probably not fed as well, If they don't like the larvae you give them they don't make a queen out of it.
