How cold is too cold for chickens?

Check em often! If signs of severe shivering, or your instincts tell you......maybe bring them somewhere like a basement. How many chickens do you have? But again, check em often. Add some warm water to feed and offer for breakfast with some BOSs or other high protein snack. Good luck from CT.

Turns out the cold bothered me more than them. They still went outside in their run every day
