Day 7 does it look like 2?

I am on day 7 and I have one egg that is super active and looks like it's more developed than the others. Or that I must be able to see better. My humidity has been unstable between 45-60 but the temp has been consistent, so I'm monitoring the air sack. My cheap incubator doesn't have vents so I crack the lid. This is the first hatch using humidity the entire time. Does it look like 2 in there or just a big chick!? I wanted to add a video but it won't let me.

Looks like 1 embryo to me. The 2 dark spots are probably head and foot.

Okay thanks! It's just a lot bigger than my last batch at day 7 and the other 3 eggs in there now. My luck it's a healthy roo!
