We have a Draper rotating obs hive. Single layer. Shallow frame over three deep frames. I saw the queen yesterday. Tons of bees on all frames. Frankly, I expected it to swarm a few weeks ago. On one side about 1/5 of the glass is covered with wax. But there is a good amount of condensation on inside of the glass on both sides. We have not opened or cleaned it since spring when we pulled a frame of brood with bees to make more room. Should we open it now for cleaning? And to remove about 1/3 of the bees? We would replace the queen when done. The frame of bees we remove would be replaced with a frame of empty, drawn comb. We would remove the bottom deep frame and replace it with the empty, drawn comb. Is this a good plan to reduce the congestion and condensation?
