Hi Dan, the hives I split from are doing fine. It’s the actual splits that were making new queens in my yard that decided to swarm.
I was pottering around about 10 o’clock when I heard a swarm. It was issuing out of a hive. I looked to see where it would land when I saw the 2nd swarm perched in a tree. I thought at first that was where the swarm was landing, however it landed in a different spot. I had no open brood at home, so I raced down to my main site & grabbed 2.
The one I watched was a piece of cake, the one in the tree was a bit challenging. The frames with open brood usually assures that they stay in the box.
The hive that I watched the swarm issue from contained 3 frames of almost fully sealed brood. Maybe they all emerged & wanted to swarm. Some of my other splits had the same thing, lots of emerging bees in quick time. Something I’ll try to avoid in the future.
