Cindy, I'm pretty close to you and we've never had a problem with hawks in the 5 years that we've let our hens free range. Coons at night and dogs during the day will be the worst you'll deal with (you may have fox / coyote where you are, but probably not).
If you have chicks or small bantam you may need to be more worried, but with our full size hens and red tailed hawks we have never had a problem free ranging our girls during the day.
