Inspecting hives today. Pulled a brood frame and saw a queen. Then about 6 inches away I saw another queen. Yes. not double vision, but 2 queens. one was short and stubby and the other long and slender. One of then kept going under the foundation to the other side. i would flip and she would go back. Then they both end up on the back side towards the bottom. I swear I could hear a chirping. then when I flipped the frame again they were fighting. And fought to the death. The short stubby queen won. Looking for some explanations. Both hatched at same time maybe. Supercede? I did see larva before I spotted the queens. And what was I hearing. Screaming? It was cool to watch anyhow.
