I agree with Michael. In Georgia, any of the dual purpose birds will thrive and do well. Rocks, Wyandottes, Reds, Orpingtons, etc. Any of the sex links will work well for you. Leghorns and other Mediterranean breeds should also do well as long as you have good ventilation to prevent frostbite. In your climate, most of the ornamental breeds should also do well, but mixing them in a flock with dual purpose or layer breeds can be an iffy thing.
The only thing I'd caution about is how wet your specific area might be. if you're in an area where the birds are going to have a wet run, you might not want feather footed birds. Otherwise, you're good to choose pretty much any breed. I say get a variety and see who you like best.
