Hello, I just hatched out this runner duckling. It's a color I haven't seen before. I'm guessing it will become a fawn&white. Which color will it become? In addition, is that a crest I'm seeing? It can only be seen on one side, but I know crests can be off-center. I really hope it's not as I don't want a duck with neurological problem, but this little guy is the only 'fawn&white' I have now. Thank you.
