I just checked my hive yesterday, May 16, after installing on April 11 (5
weeks ago).  Since I'm new at this, I'm not completely sure what I was
looking at but it looked like swarm cells.  I checked a book later and it
appears that I was right.  I put a second deep super on yesterday and I'm
going back in today to take another look.  Hopefully it's just swarm cells
and no queen larvae.  I hope adding the second super will convince the bees
to stay put.  It does look like an early swarming season here in Michigan,
too.
 
I did read in a book that if one should blow up a hive that is intent on
swarming, then they probably won't swarm.
