I made a few experimental beehives last year. They are frameless hives, so the bees can make their comb in a natural way. The hives are basically just empty boxes with a couple of thin wooden supports to help support the comb.
One of the hives failed in a cold snap this February. Last weekend we harvested the honey. We ended up with 2 ½ gallons of honey from one failed colony.
Watch the video to see what the inside of a natural beehive looks like.
