I don't do facebook, but you might also try there. Being in Florida you should still have a lot of options this time of year. In fact one guy I bought silkies from had his eggs shipped from a breeder in Florida. If you have any feed stores, might be worth calling them. They often get them from the hatchery. But they also might know who the local breeders are and they usually have lots of contact with the 4H kids.
Do you already know what you're looking for? Color pattern, bearded or non bearded? While blue is one of my favored colors in birds that's not true for Silkies because they are too close in shade most the time to tell apart from black. But how cool would it be to get Lavender?! I currently keep black and paints, as well as a splash and some blue boys on their way out of my flock.
