The coop is under construction and I'm set to pick up my mini-flock this weekend! I've been spending an unhealthy amount of time on this website the last two weeks, trying to absorb as much knowledge as possible! Hopefully I don't screw it up too bad! I'm getting 5 adult hens and a 5 month old rooster from a local 4-h kid (all buff orps), We're building a 4'x12'x6' coop/run combo in the back corner of the existing barn. I plan to let them free-range during the day after a few days of confinement to the coop(I've read that's the best way to ensure they go back to the coop at night?) Anyone experienced chicken heads in my area have suggestions for overwintering the flock? Can I pretty much rely on their instincts for when it's too cold for chickens to be outside? Or is there a standard temp when I should keep them in the coop for the day? Any other advice is greatly appreciated!!
