I've added a third super (or box) to both hives. Prior to putting the topmost one on, I put a queen excluder between the lower two boxes and the new, topmost one. This metal mesh grate allows the smaller worker bees to move into the upper super, but the mesh is too small to allow the larger queen through. By keeping the queen out, I make sure that the queen doesn't lay any brood (or babies) in that area. That way, the contents of the upper supers consist of honey only.
So all the honey above the queen excluder is mine ... mine I tell you! And everything below provides stores for the bees so they have carbs (honey) and protein (pollen) to overwinter.
