Question about one of my incubating eggs

[motheroffour]

Hi everyone. Ok so I have a question-I have an Americana egg that was laid around June 13th-I candled it this evening and when your looking dead on at the egg (up/down) half the egg is dark the other half is light and the bottom of the egg has the air cell. Does it sound like it's alive or dead. I also see no movement. But wanna still give it a chance til I know for sure. Thank you.

Adding on something. It's possibly an egg from June 10-13.

Very sure looking back on calendar and it's the 10th it was laid on.
