Another thing you can do, is reverse the brood boxes. I reverse mine as the situation warrants in the spring and early summer. That way, she is filling the bottom box and as she moves up, the emerging brood is making room again. Weeks later the process is repeated, and then we're off to the races. It helps retard swarming, keeps the queen down without hindering the bees efforts to store honey past an excluder. And I agree with Carbide about queens moving up. They move up easily but the bees have to twist her arm to go back to the basement, so I help them. George Imrie has alot to say about reversing brood boxes and swarm prevention, as well as supering. He's a crusty old bird, but he's been doing it a long time. Look up his pink pages.
