I have been using 5-frame nucs to draw foundation. By staking the boxes with foundation (plastic or wax) over strong 5 frame nucs and with heavy feeding you will be amazed how quickly the frames are drawn.Multiple nucs, rotation of the frames and continueal feeding will generate quanities of newly drawn frames for replacement, new hives, or additional nucs. I use top feeders that are kept full at all times. I believe that the confined space is just right for the bees to work upward in an attempt to expand their nest.
