Cheetie, I am in Stafford, VA. I just had my second flrdge a couple of days ago and I expect another nest in a couple of weeks. In most years I have had 3 nestings.
We mentioned in another thread that the Bbirds may start a new nest from a couple of days to 3-4 weeks following the fledge of a brood. It depends on when the female is ready to start a new brood.
The only thing that you can do is clean out the nestbox and wait until they are ready. It sounds like you have all the basics. Just be patient.
For a lot of good information about monitoring bluebirds you should visit this website. It is probably the premiere for bluebird information source in the web.( http://www.sialis.org )
Happy 4th
