Saturday I attempted my first split. I took a frame of open brood, a frame of capped brood, a frame of honey, and a frame of pollen (at least that is how I would describe the majority of each frame) and put all of that in a new hive body with 6 empty frames (deep). Yesterday and today the front of the donor hive is completely covered with bees. The hive was pretty crowded when I took the frames, but there were no queen cells Saturday morning. Would you say they are prepping to swarm? Anything I should consider to stop the swarm? I have empty nuc boxes with frames in the area in hopes of catching a swarm. Maybe I will catch my own?
