Drake bill turned greenish blue?

[crazyducklady5]

I am concerned as the bill on of my two drakes (ayelsbury is my best breed guess) has started to turn this greenish blue color. It was originally a pale pink color with a little orange. When I noticed the discoloring several weeks ago I thought it might have been a bruise, but it has not improved since then. Neither his behavior or appetite have changed. Does anyone know what this might be and how I can help him?

First of all he is super handsome!
I could be wrong but I dont think its anything to worry about , most of my pale pink/orange duck's bills have gradually changed color too

Hi.

He is a beautiful drake!

I think you have nothing to worry about (unless you want to show him) : sunlight - and also, maybe food...? - probably did affect his bill colour.
