With almost 20 chickens in possession and having raised them since March of this year in my back yard, I believe I have reached "expert" status on BYC, Robert, so I would be happy to provide you any sort of advice you need.
I believe if you took the progeny from Mr. Silkie and your Red banties and cross them in with some of Lacy Blue's Andalusians, you have the makings of a patriotic colored Red, White, and Blue hen. If you start now and work fast, you just might have chicks in time for the Fourth of July.
If you like, I can draw you out a genetic chart with Punnett squares and everything so you can even back it up with science!
All the best.

You know, I read this post shortly after you posted it and I'm still in shock! Please tell me you are joking around!
