Nuc swarming

So the other day I took two frames from the pent roof hive, including about 6 queen cells. This evening it swarmed.

It landed on some delphiniums which then gave way, bees are heavy when you have lots of them in one place. Not the best first swarm for me to have to deal with, one on the floor. Due to access restrictions I collected the swarm with three shoeboxes. I had to chop down the flower stems to get to all the bees and take a bit of soil. I put out a white (ish) sheet and on a small table with the sheet leading up to the entrance.
