Hi pg55,
With the recent phase-out of fighting chickens in Louisiana, maybe that is where these birds are coming from.  I guess some breeders may just start dumping birds.  You could knock on a few doors and if they no one admits to owning them go ahead and pick up a few.  The hens will lay eggs even without a rooster.  If you think you want chicks at some point grab a roo or two, but be prepared to seperate them.  Most roosters will fight for breeding rights, no matter the breed, especially if kept confined.
