Bee-Bop, I wonder if the bees have sealed off MOST of the entrance and left only a bee space, but you think it is totally sealed off?
. That would be OK, there could still be some room for condensation to escape. Once the bees cluster, that space could be left more open by your removing the propolis with your knife. The bees know best. Perhaps the colony is a smaller size and they feel that they MUST seal off most of the airway? You will hear more comments, but these are my thoughts, great day in this beautiful life, Cindi
