When you candle an egg, is there stuff on just one side of the egg?

Here is the egg I was originally referring to:

It could be okay. I candled an egg and it was like that. The chick is fine.

Oh. It hatched!

I have a dark mass on one side of egg also and it’s my first time incubating and candling. Day 7 does anyone know what this means?
