Milk poop

[Artoflife90]

Hello Everyone! My drake has been pooping some milk poop recently. Not all of his poop is coming out this way though. He also has some regular green poop. Any idea of what it could be? Here pictures below of his milky poop and regular poop.

Looks like normal duck poop. One thing to watch for with ducks is neon green - like fluorescent in color. Of course if you ever saw blood, that would be concerning.
