Re: Bottom for a Queen Castle
Adrian is right. We started just splitting a deep box into 3, 3 frame compartment and giving each an entrance on opposite sides. Screwed on piece of plywood for bottom. This put bottom of frame about 1/4 inch off bottom.
Turns out, a lot of swarm cells are on bottom edge of frame and extend below frame 1/2 inch or more. We pulled off all bottoms and added 3/4 ripper around box then put bottom back on.
Also returning queens can end up on bottom and not find way back into hive.
