Ok last spring I got 3 chicks, one duck, one pilgrim goose. I also ignored the sheds I had and bought a metro chicken coop with upstairs/downstairs. After the chicks could stand the weather I put them in the coop with fencing about 30 feet circumference around. Chicks went upstairs, goose and duck stayed down below on ground. After they got to size, I left the gate open to their enclosure for free range except for at night. Now it's getting cold and no one will go into the metro coop that I doubled walled with hay for insulation. The chickens roost on the roof of the coop, duck and goose sleep on the side of it. I'm bringing them into enclosed for winter (4x5) in garage with dog door to outside and kids pool with heater but I was hoping to get through until Jan/feb. will they freeze to death from bird stupidity before then?
