Hello, I just joined. I have recently convinced dh in the chickens. I have been reading and researching, Hoping to get a small flock of 3 and a tractor in the spring. Would love to know what set up I will need for winter protection in GA? I am zone 7b for cold hardiness. Will chickens be ok in a tractor w plywood enclosure? Do I need a sturdier and bigger coop for winter? Any best breeds for laying and forage for our climate or breeds to avoid? Do I need to look for both heat and cold or just heat on the breed selectors? Thank you in advance for all the help!
