Sounds like their in the process of superseding. If you want more hives you can take a frame with capped queen cells on it and two more frames and put in a nuc.
Or you could split the box 50/50 making sure you have cells in both boxes.
Or you can leave them alone and let nature take its course. The only risk to this is if the new queen doesn't make it back from her mating flights. Her chances are probably 80% or better.
If you have a nuc box handy it's good insurance to throw a few frames in it and if one doesn't make it back you can combine them with the one that does.
Supersedure is a very normal occurrence. Most of my hives will do it once a year or so.
IMO trying to introduce a mated queen is risky. If you miss one cell the new virgin will kill your new queen who is probably way inferior to your home raised queen.
