I stepped out of my bee trailer about an hour ago to see a number of bees in the air. On one side of the door, there were bees covering a hive that had been empty until now. Looking to the right, there were two boxes with bees working in and out. I had no bees here yesterday. Is it 3 swarms, 2 swarms, with one getting mixed up on the two boxes side by side, or is it only one swarm that split when they got here, and will reunite later today? What is your guess?
