I switched to 2-1 a week ago. As far as the queen, I would at a minimum try and pull your queen and put her in a small nuc to hedge your bets. Once the cell hatches, there is a good chance she gets the ax. Then if a mating flight fails, you can recombine, if it is successful, you can make your decision on which one to keep. I had a successful supescedure in late August. She is fat and laying up a storm. Good Luck. G
