odfrank, how do you set up entrances? One at the bottom, or top, or multiple entrances? Airflow might make a difference. Just speculating from my own lack of experience.
My 4 hives are all right against the top and have been all winter, but that is due to poor flows last fall so they had essentially no stores and are subsisting off the sugar I put on the top. Sounds like your situation is different though.
