Why is my duck egg turning black after incubating (due to hatch in 9 days)

Yes, it appears to be growing but I don’t see it move

J4 is the black egg, (they are Cayuga eggs and supposed to be slightly black but they never have been and this one wasn’t until a week ago? )These pictures are what the entire egg looks like through candling and it has a very very mild boiled egg smell

I think either it quit weeks ago or it was never fertile, I'd pitch it, I'm sorry.

I took it out I’m a bit disappointed because I just lost 4 other eggs to incubator malfunction. And lost a duckling some how.
