two queens

[troutstalker2]

  I made a spit about a month ago with a queen I bought from kelley. I found a queen cell about 2 and1/2 weeks later. I thought It was a supercedure, not too uncommon. Went in yesterday and found a new queen (mated). I looked futher and found the kelley queen (marked) I think the newest queen must have been in there a week or so I would think. Too week of a hive to want to swarm, any ideas? Will queens just coexist for a while?
  The kelley queen seemed to be doing fine, good brood producer so I did another split with a little help from a very strong hive.

you can leave them.  it's not to uncommon and usually a good thing.  if there are enough bees, you can use an excluder and another box and put one up and one down.  that way you get the benefit of two queens and less chance of one killing the other eventually. 
also do a search here.  we had a conversation about doing two queen hives not to long ago.
