I would say it depends some on how bad they (supers) are. That is kind of how the Langs I started with were. I had built new deep brood boxes before I got them. I got them the middle of Dec. It wasn't real cold, and I changed them out the week I got them home. I had the deep they were in, set the new deep beside it, and moved the frames over. A few months latter I added another deep. Good luck to you and YOUR Bees, Tireman.
