I am planning to overwinter a few one-deep colonies on top of other colonies. The top most colony will get the regular insulation - a newspaper and a stick facilitating top ventilation.
What about the lower colonies - do they need some top insulation or will the higher colony act as sufficient insulation and prevent moisture condensation below? [I will provide the lower colonies with some top ventilation into the higher colonies.]
Thank you.
