Is the duck egg bad?

[OreoPlymothRock]

I am incubating 4 duck eggs. They are in their days of hatching, but I think one is bad. I smelled all the other eggs (their shell) and they don't smell. But the one that I think is bad smells horrible, I candled it and I see no distinct veins. Help?!

If it smells bad I would get rid of it before explodes

Thank you for the quick reply! I got rid of it, I candled it before getting rid of it and it looked like a chemical concoction going on in the shell. Along with internal shell erosion.
