Help ! 1st Time Incubating Duck Eggs!

[TNTHobbyFarm]

Hello everyone, This is our first time incubating duck eggs. I have five that are due to hatch in 7 days (?) Today I went down to check on them and one ( dated 2/10)

now has a small “ star” crack. I’m not sure if this egg is now bad or hatching early. Can anyone please give me some advice on what to do next.

Looks dead and rotting, I'm sorry. Can you shine through the bottom with the room lights off?

Thanks for the quick response. Here’s a picture of the light shining from the bottom.

Yes, unfortunately I think it's a rotten egg
