I live in Wisconsin, the last two days, and this whole coming week is in the negatives. My chickens are living in my attached garage right now because we didn't get the coop done before winter came. The have pine chip bedding, and a house to go into. My garage is reading about 25-30 degrees. I change their water morning, afternoon when I get home from work, and evening before bed. I found one of my buff orpingtons laying down and not wanting to stand. Everytime I tried to get her to stand, she would drop down. I got her to drink water, and eat some food. She seems alert, but won't stand and is acting cold. I turned a space heater on, and heat lamp to warm it up in there, but shouldn't they be fine with the cold? There is no drafts. I only use the heat when I'm home. I don't trust the heat source when I'm not home. Out of all my buff orpingtons, she is the biggest. All of my other ones seems fine. They are 17 weeks old today. Is there anything else I can do to help her? She doesn't seem sick, but I'm worried about her. Any advice?
