I looked out yesterday to see a swarm high up in a tree. Yes, I would bet it's from one of my hives. Now to go look for queen cells. I will probably combine them with another colony. It's pretty late in the year to allow them to requeen themselves. As for the swarm, they are still hanging in the tree. There aren't any nectar sources out there unless it's soybeans. I put a brood box out with an old brood frame. If they move in I will figure something out. If not, it's been good knowing you.
