its not the bees.What causes this building behaviour in the hive. There are 6 frames joined together by comb. I was wondering if the spacing between the frames results in this behaviour.
It looks to me like the rebate the frame lug sits on has been painted green. In some of the photos, it appears to be a 'thing' between the frames. But I think it is just the green paint visible behind the parts of the frame.What are those green things between the frames? Spacers? Are they used in supers to draw deeper honey comb?
