Re: When to add 2nd box of drawn comb.
I agree with Mr. Beeman regarding the arrangement of the frames. As far as when to add a second box, I'd be looking at when the queen is laying a lot of brood in the center frames extending out to within a few frames of the edge. For me (and this is just my opinion), I like a colony that is taller than wider. When I add a box of drawn comb, I add it when I have about 6 frames actively worked down below (I run 10 frame mediums). That means that the 2 frames on each side are drawn and may have some activity from the queen but those frames are not filled with brood. That's conservative. In reality, I probably add that box when the outer frames have some brood but not a lot. Again, that's just me.
