This is a open question for education only. I can't convince myself that I need 5 frame nucs to raise bees for myself. I use a 10 or 8 frame box with a sliding division board. As they grow, I add a frame or two. If it's a deadout, I just use that box and frames. Maybe climate has something to do with it and feeding. I can use inverted feeders year round. Just seemed to me that leaving them in them same box was less disruptive to them and less work for me.
