Re: Pyramiding Up - Partial Checkerboarding for newbeeks?
It works well for me. As long as there are enough bees to cover the empty frames when you insert them into the existing brood nest they expand rapidly.
Empty Comb vs. Empty Frames - in my experience there is a spring timing issue that I need to be aware of. In very early spring if empty "frames" are inserted into the brood nest they are usually ignored. They do not seem to be interested yet in building comb. With empty "comb" they will immediately expand into it. Progressing further into spring a point is reached when comb building will begin right away when inserting empty frames into the brood nest. I'm not sure if anyone else sees this, but that's been my experience with opening up the brood nest or pyramiding.
To everything there is a season....
