The past few days we've had 0 deg weather yesterday was really cold and windy. I went out to check for eggs and then water and feed for them. I noticed a hen laying in the corner not moving that much other than moving her head around. I went to pick her up and noticced her legs were sticking out the side instead of her sitting on them. I picked her up and her feet where stiff. thinking they were frozen i took her inside and placed her in the tube with some water in a bowl for her. she drinks from time to time but she is not moving that much once in a while i will hear her move a foot but that is it. if i touch her she will close up her feet and move her head around. i have tried to standing her up but she falls over and she is not moving her wings either.
