First of all I use all 8 frame deeps. I have heard many like to winter their hives Mike Palmer & Michael Bush with one brood box and a super of honey/pollen above it.
What would you do if you had two deep boxes of brood? Shake the bees into the lower brood box? Use the excess frames to help other hives? Or would you keep the double brood box setup and just have one deep super over both brood boxes?
Thanks for your thought/suggestions?
