I've got a couple of boomer hives that have filled 5 shallows already a piece and I just placed a sixth on today. Privets about gone, clover is still in, but what else in this area could be adding to it? This is a super strong flow. The last supers that were added were filled in less than a week with white burr wax everywhere on top of the frames. I'm not complaining, just dreading using a step ladder to pull honey soon.
