i would keep 10 frames in all brood supers. my mentor used to keep 9 frames in honey supers so the wax would be drawn out farther and make uncapping easyer.
Ok, now I understand! I think I'm failing at this "moving undrawn frames in" part.I remember hearing Gary say he runs 9 drawn frames in a brood box. He likes the extra space. The key word is "drawn". The bees will make a real mess if you put 9 undrawn frames in there - a lot of cross comb will be built. Adrian.
