Air Cell already on Day 1 Duck eggs?

[Wonder Quails]

Hi!
I was just candling my eggs on day 1 to check for hairline cracks when I noticed
something strange. One egg had this air cell that made it look like it was
on day 7 or something. The air cell looked strangely white and glowing up but the yolk had no embryo
or veins(yet). Is there something wrong with my egg?

Thanks

Here's day 1 pic of duck egg. You could definitely see the air cell clearly.
