    My queenless, cutout bees working brood comb and hopefully making queen cells are now 4 days in a 36" Top Bar hive box. They have a 1 3/8" round entrance on the lower part of the end of one side. Screen bottom. Being concerned about robbing, I'm thinking of reducing the entrance hole size. How small do you recommend?
