Thank you all so much. "Ruby" our chicken is very social and we definitely will find her a friend. We only let her out when one of us in the yard with her. My 7-year old kept her company in the rain yesterday. He doesn't want another one to get hurt. NurseELB I would love to take yours off your hands, but the one I have left was the "top hen" and most agressive in my coop and I'm afraid she would not be a good match for yours who is terrified of other birds. Thank you for the offer though.
I don't think I could handle chicks right now. I'm so new at this that raising chicks in the winter seems too much. I need to do a lot more research before I tackle that one.
Today our whole family was in the yard building the Fort Knox of penned areas and putting in a new, smaller chicken coop, that fits 3 (just for now because it will be easier for her to keep warm in. Our other one is 8'x8'x8') and Ruby hung around us all day. She definitely needs a friend.
Sourland... thanks for the tip on supplemental heat. I'm glad I don't have to worry that much about the cold.
Thank you all.
