B,
I weighed (lifted up the back side of the hive) all of my hives yesterday. One was real light. I placed a medium super of capped honey just above the brood chamber and moved the 95% empty that was above it, on top of full one. It was too cold to mess with the bees. Opened it, switched them around and closed it up. Next cold day I will remove the empty super. If I didn't have that full super I would have to feed that hive real soon. That is something I try to avoid. Adds too much moisture. If I have to I will probably use dry sugar above the brood box. That way they are only using it for food and not storing it.
