Aylett, VA 10-frame double deep Langstroth
In my mind, a single 8 frame medium is not a nuc, it is a too small hive. If you are running medium frames, use two 5 frame medium boxes for the nucleus colony. I winter my nucs in single deeps, 5 frames with a feeder on top, but have built the double mediums for a friend.
