Ok, I found a pic of my ducks with the green on their bills. This is when I first got them, so they are approx. 4 months old in the pics. One turned out to be a drake! The other three, I am pretty sure, are hens. Only the one has the curly tail feathers.
Here is the pic. You can see that two of them have green on their bills. One much more army green then the other...the one in the back. The one in the front looks almost blue green in the pic, but is now very greenish tinted. They are about 6 1/2 months old now. It really is just the coloring of their bills. I wouldn't worry about it on your duck, unless it is very obviously something "growing" on the bill. Can you post a picture for us? Thanks.
