One of my colonies recently superceded their queen.  She started laying eggs last week.  Today I inspected her brood pattern, and it is good.  Except I noticed that on one frame of brood there were two eggs in most of the cells.  It is just that one frame.  I couldn't lay eyes on the queen, but my first instinct is "two queens"  I am relatively new to beekeeping, so any ideas or comments would be appreciated.
Thanks,
