If the only sign is multiple eggs and sporadic laying pattern, it may
     just be a sign of a new young queen.  I have seen that in a queen that
     turned out to be doing just fine a week later.  With laying workers
     the eggs will be on the side of the cell rather than on the bottom.
     And you will usually have more than just two or three, at least in my
     experience.  I'd be interested in what you find out.
