why haven’t sheep evolved to “right” themselves if they fall on their backs?

Please explain sheep and any other animal really, that can become “cast” – isn’t falling down just a normal part of life? How is it that they can’t get back up themselves and will die from what I think of as a basic fact of life?

If it doesn’t keep you from passing on genes to a new generation that can pass on genes, a flaw isn’t going to get fixed by evolution.
