I tried putting the inner cover between the hive body and the super to get the bees to 'rob' out the half full supers down into their hive bodies for the winter. Doesn't seem to be working. (the super is going to come off for winter) What do I do with these half-filled super frames? Do I keep them in a box for next spring? Do I freeze them? I'm surprised I can't really find much on this topic - surely everyone deals with this.
