My drake is right around 6 months old and right above the bean on his bill a whitish spot formed. I had read something awhile back (when I didn't have ducks) about this occuring to someone else's drake and remembered that they had found out by others that this was normal and okay. So I figured this was okay, well the other day when I looked at it, on the side of his bill right against the whitish spot the yellow was a different color and it looked like it was coming off a little. Kinda like when you get a sunburn, I guess. There is nothing else that indicates a change and it does not bother him and he is not sick from what I can see. If anyone has had any experience with this or could know what it could possibly be, please let me know. Thanks in advance!
