Nice set of videos Bailey. I have had bees for 3 years now and I still have not seen a hive exit for a swarm. My wife was in to house last year when the observation hive, in our the closed -in-patio, started to swarm. She could hear it in the whole house and went out there to see it exit. It stayed just outside because the week before I had switched to the QE opening knowing it was going to swarm. I ended up spliting out 2 of the 3 frames to a new hive. I just split the 2 frame hive again this week.
