Egg hatching?

[sarah4hchickens]

I have a broody duck that had been setting on a collection of duck and chicken eggs for a while. I don’t know the exact date but around 20 days probably. Is one hatching or did she crush it? All the other eggs (10) are fine.

Is it a duck egg or a chicken egg? Kinda looks crushed but it's a little hard for me to tell
