I just did an inspection of one of my hives and I found 2 queens. This hive was a package installed May 9th 08. They almost have the 2nd brood chamber filled and are doing great. The first frame I looked at I found an unmarked queen and thought that they had swarmed without me knowing. Then I flipped the frame over and I found my marked queen. Also, I just captures a swarm 2 days ago and that hive is about 5 feet away from the 2 queen hive. The unmarked queen is bigger than my marked queen.
Questions: What happened or what is going on? What should I do? Could my swarms queen have gotten in somehow?
