    I have two mallard drakes. They are not rouens, but true mallards. They were hatched in June, and have been in breeding plumage for months now, but one of them still has a olive green bill. Is he lacking some mineral or something, or is it just a rare genetic thing? He is extremely healthy, and his bill isn't soft or moldy or anything like that.

    it may just be a genetic thing, but to be safe what is his diet ?

    and when you say olive green do u mean like really olive green or a just really dull yellow?

    Mallard and Rouen drakes can have a bill that varies from a bright yellow to a drab olive green. It isn't a defect or a sign of any malnutrition. It's just his bill color! It's sort of like the black spot on the end of the bill, some have it and some don't.

    I've seen a few drakes with a bill that's greenish or even looks blue-ish. They all look healthy, but they might not be pure breed mallards.

    He eats All Flock, and the rest of the ducks eat it too. My runners have extremely bright yellow bills, and everyone is healthy.

    I've never seen a mallard without the black spot, that's cool.

    @Kroelies , that is almost exactly the color of his bill, except he has a black line in the middle. He is definitely a pure mallard.
