I've got a hen and 10 chicks living in my garage at the moment in the middle of my stack of hay. I've got a coop being mended at the moment but need to know when I can put them out. They are a week old as of today. I live in Southern GA and right now our temps are in the 90s during the day and 60s at night. How old should the chicks be before I put them outside in the coop? I'm completely new to chicken ownership so I have no clue.
