Hi we are new to ducks and one of our Pekin Ducklings(2 weeks old) has a strange looking green spot on the bill. I have seen the pics of the mossy look and it doesn't look like at all. It almost appears to be on the inside and you can see the shadow of it from the out side. I am just worried about them I don't want anything to happen they are our new feather children. Thank you for your quick replies.
