Muscovy egg

[Vanillaandbean]

Hello everyone! I have a Muscovy egg, and I'm wondering if anyone can help me identify a certain part inside. There's something in the air cell that seems to appear and disappear frequently. Sometimes it gets dark, and I'm guessing it might be a foot. Does anyone have any insights?

I can't tell but it could be the case. It looks like it's soon to be hatching.

Hopefully, you get a gorgeous little Muscovy duck soon!
