Is this duck poop normal?

[Djgm]

So, my little over a month old Pekin is eating/drinking behaving totally fine. But today I noticed her poop looking charcoal black. Being a newbie, I just wanted to see if it’s normal, or should I be worried?

Eek! I've never had this happen to me before, but if it did I would be worried. Unless I knew my duck had been eating blackberries or blueberries.

Omg I didn’t even think of the blueberries! Whew. I’ll keep an eye on her just in case, but she was a little piggy with them earlier!

Oh if she ate a bunch of blueberries then I'd bet that's it! I'm extra careful with my ducks, so I'd probably not give her blueberries for a couple days to make sure it goes away. Then give her a bunch and see if it comes back. You'll have your answer.
