Top of bill peeing: 6 week old mallard duckling.

Tonight, I noticed that the top of my mallard duckling's bill looks like is getting ready to peel starting at the base and has already started in one spot. Is this normal?! peal

I don't know that it's is developmental, but I have seen that type injury here. Just be sure to provide lots of fresh clean water with a bit of ACV added, should heal up quickly.
