I will be finishing up my coop this weekend, just need run the chicken wire around the perimeter, which I am picking up tomorrow. My question is: I am very new to chickens. Should I start my flock (4-5 hens) now, or wait until spring? I don't have a heater setup yet. I am a few miles north of Atlanta ga, it's pretty warm here, do I need a heater in the winter? So someone completely new, would now be a good time to get chickens, with the winter approaching?
