I was out of town for 6 weeks this last fall, and it is my belief that my hive self-split and swarmed. I'm guessing that because the amount of honey in the sups prior to my going away was much more than when I got back, and the hive seemed weakened.
I decided to let them winter, and then requeen today.
When I opened the hive I could not find the queen, but I did find an open queen cell. I'm guessing they had started the process of requeening themselves, as there were also a good number of drones (which made finding the queen even harder). I don't think I had a worker-laying situation (were not that many drones).
So I bought a requeening frame, and installed the new queen in the hive.
If I missed the old queen, what kind of behavior can I expect to see when I go to let the new queen out in three days? Is there something I should do in the mean time?
