I transferred a strong colony from a nuc into a larger brood box this afternoon. It was a bit of a game as I was on my own and it involved a second colony (weaker) also being united. It always amazes me how the bees march into the hive to find the queen.
I tried to take a video - it wasn't terribly successful and as you can see I didn't know how to turn it off at the end. But if you watch you'll see them almost running out of the smaller box and into the bigger one. Enjoy!
