I've read about top entrances and most folks, including myself use bottom entrances, but what about mid stack entrances? Would there be any advantage to having the entrance to the hive at the top of the brood boxes and below the supers? Seems to me that it would save the bees some time in getting to the supers to put up nectar during a flow. I'm sure someone has tried it but I didn't find any results when searching the forum.
