This was a swarm which was caught twice. The first time they were in the box for only about 24 hours and decided to leave. Fortunately, I caught them again and put them back in the same box with a queen excluder in the bottom so queen couldn’t get out. I felt mean, but didn’t want to risk loosing them. They’ve been in there now for one week and have completely drawn out all the combs and filled them with honey and brood! There in two boxes now and quite happy.
