Good news! I separated Katy from the others and had her in a box with straw and water. My husband, a farmer, put the box on its side so that she could come and go. And she has made a wonderful recovery. She has drunk a lot of water, and eaten grass and insects as she wanders around. I discovered she was under the horse float, behind the collie dog because she was 'talking' to me. Go Katy!
