I took 3 frames of brood, with bees, minus the queens, & combined them in a 10 frame box flanked by frames with foundation. This is part of my preemptive swarm control strategy. I bought the box home, which is far enough so the bees wont return to their original hives. Now I’ve broken that into two nucs by giving each nuc the same number of emergency queen cells. Spring has sprung here, well & truly, which is evident by the amount of brood on the frames. Here’s my video.
