I've got a young goose who has one wing that is carried very high over the back. I don't mean just the tip, I mean the entire wing. I've never seen anything like it. Her wing is almost over her back instead of along her side.

I was wondering if anyone has any idea about what has caused this.

She's from a purchased egg, fortunately, not my own birds. The other hatchling has the worst case of angel wing I've ever seen. So they are both going into the freezer. Whatever it is, I won't be breeding the problem into my own flock. Too bad. The bird with the hunched wing is otherwise quite gorgeous.
