A question that I should know the answer to but don't . . .
Two weeks ago I put a medium super with drawn comb on each of my two hives from splits. They've been filling up the comb with nectar pretty good (about a third full as of last Sunday), and are to the point now where they are so full in the supers that they are spilling out of the oval hole in the inner cover. Which tells me I should be adding another super. I only have frames of foundation to add on top of the hives though, so here's my question: do I put the next supers with foundation on top of the supers currently being filled up, or above the brood chamber but below the drawn super? I want to be able to pull the filled supers off in a week or two (or three) to extract them without too much hassle, and replace them empty.
