One of my chickens was accidentally left outside last night. I found her on the ground this morning, there was a puddle of water underneith her (I'm guessing melted snow from body heat), she was huddled down, neck pulled in, eyes closed. I brought her inside and set her in front of the woodstove, but she hasn't opened her eyes or done much moving. I know it got below freezing last night, and was wondering if there was something I could do to increase her chances of getting through this, or if she's a gonner. I did try giving her water, but she just pulled away and closed her eyes again.
