ABSTRACT:
A ventilating inner cover, for a beehive wintering outdoors, is disclosed. The inner cover provides adequate, but not excessive ventilation while preventing a draft through the beehive. The inner cover embodies a ventilation channel that connects the top-center volume of the upper brood chamber with the outside atmosphere. The ventilation channel is simple to construct, being formed into the structure of the inner cover.
