For 3 weeks now I have had 2 queens in one hive laying. I had not looked in the brood box in a while then 3 weeks ago when I looked in there were supercedure cells on several different frames. Most had been distroyed but one had emerged. I found her on another frame and she was a big pretty girl already laying. I went a few more frames and found the marked orignal queen on another frame and she was also still laying. I figured what the heck I left them both in the hive. Well I looked last week and both were still in the hive laying. Today I looked and still both are in the hive laying. I have noticed that the new queen is always on the left side of the hive and the old is always found on the right side. Whats the worse thing that could happen with leaving them both in the hive?
