BSCOTTM; if there is a flow on the bees will build the super frames out. If no flow and you want drawn frames you have to feed them. We never feed just to draw out super foundation; we let the bees do it on their own. We place new foundation on them during our flows, especially citrus, and they draw it out and fill it in a matter of a few days. How else do you get drawn frames for next years splits?
