Last week I was able to catch up with Hal and ask him about his log hives.
The hive cavity measures about 10 in. x 10 in. x 36 in. (59 liters) There is a large observation window in the back covered by a wedge of wood.
I admire his spunk in trying something different and his attitude for not feeding, treating them, or taking their honey. And I’d love to get a swarm off that hive.
