If you segregate your extracating frames from those in which brood has been raised, as I do, then there is no advantage in having all your frames the same size. There is a tiny advantage in using deeps for brood: The honey arch is about the same width in deeps as in mediums so two deeps will have more brood raising area than three mediums. Obviously, the beekeeper will provide enough brood raising area regardless of the depth of the frames. Dan __________________________________________________ Do You Yahoo!?
