I just put together 30 Illinois (medium) frames & foundation. I intend to gradually convert over to all medium supers, using them for brood boxes as well as honey supers. Do I vary the number of frames or do I go all 9 frame or 8 frame or what? At present my brood boxes are 10 frames and my honey supers are 9 frame because I've found the bees do, in fact, draw the comb out deeper in the 9 frame. How many Illinois (medium) supers should I dedicate to brood?
