Ruthie Bader Hensburg, One of my three month old chicks died in the night . I went out to “tuck them in” before I went to bed as usual. It was a couple hours after dark but they were all awake huddled together on their roost as they like to do. She was on the next roost down from the other 9 but that is not too unusual. When I went out to open the door to the run about an hour after sunrise she was stiff and cold on the concrete floor with no apparent injuries. I know this is part of keeping animals and I probably will not find an answer but I thought someone might think of something I missed.
