HELP! What is this in the egg? Is this the air cell of the egg?

Hi, so I am incubating eggs and I got this egg that was alive but I checked it today and it was dead. I noticed that something at the bottom moves. Can anyone tell me what that is? I've got another live egg that has that same thing move but less and I am worried for the live egg now. I recorded this video of egg that has a dead chick and posted it on YouTube, please watch the video and let me know what it is if you know. Please Help!? What is it? Is there anything I can do?

The Empty white space is the air pocket, but the thing that might be moving is probably the chick + fluid that's pressed against the membrane.

Is that fluid bad? I believe the eggs I am incubating need more humidity in them and I am trying to do my best to put more humidity out there but when I saw that 'fluid' I was like that can't be water can it?It will it kill the baby inside?

Eggs are completely liquid until the chicks is pretty much ready to hatch and your eggs is now a solid organism. The yolk will float around even in an infertile egg, completely normal. Dead embryos tend to clump up after a couple days and float around in the remaining liquid, that sloshiness is normal for a dead embryo and a sign the egg has died. A live embryo will slide around as well but it is more like oozing, think honey vs water. The egg died, it has nothing to do with you or the humidity, don’t panic, it is part of incubation. You will lose some.
