Lloyd, with the 1 inch upper entrance (that would be covered by the top
cover) how do the bees keep warm. With temps below minus 20 F, and heat
rising, wouldn't the temperature inside the hive get cold enough to freeze
bees on the outside of the cluster and also limit their ability to move
stores around.
