SPLIT RAIL FENCE
That sounds oh so VIRGINIAN
I just completed nucing swarm # 4 yesterday, 6 April. Ahem, from simple bushes and one from the lawn, regular grass, really.
I would put swarms in a nuc, no more that 5 frame 9 5/8 size, free of any other frames of anything from any other hive. A liberal spritzing of honey laced sugar water seems to help in the smell department, and how. I spray all the new empty frames, the cover, the box sides, everything. The most amazing thing happens when you spray sugar water in the box.
Once the swarm has accepted their new accomodations, then I would add some frames of brood from another colony. Or you can do a combine of the nucs using the newspaper method. Suggested newspaper? Why the Wall Street Journal of course.
