It might take some time, honestly I have them laying the next day most of the time. I don't know why people say to order a new queen when you had plenty of queens right on hand but what's done is done and I'd give them a week and check for larvae.
On a side note regarding this, 6 or 7 is more than I'd expect for number of queen cells in a supercedure, although I'm sure it's not unheard of. However, many of the details that you provide make it sound like you were actually in a post-swarm scenario, not a supercedure. That number of 6-7 should be given attention next time you see that happen....I had lots of capped supercedure cells (I think 6 or 7) even though the queen was laying great...on May 23 I went in and scraped out the supercedure cells. At that time I wasn't able to find the queen to kill her, but there weren't eggs or uncapped larvae so I figured she must have either died or left the hive...
