Rotten duck egg?

Is my duck egg rotten? It’s not moving and it smells, it’s quite liquidy inside.

It looks much alive! Don’t trash it, you never know and you don’t want to kill it! Duck eggs might naturally smell bad if it’s not clean, Ducks are messy creatures, but extremely cute!

Looks like a possible death. If there's no movement on two consecutive days I toss (sometimes, they just down't want to move. I mark the eggs i'm suspicious of and keep an eye on them).

But since it smells bad, toss it. Duck eggs do not naturally smell bad, and it could infect the rest of the hatch by being a source of bacteria.

Good luck with the rest?
