Possible staggered hatch?

[Gooseboy04]

I have 6 duck eggs in my Brinsea mini advance incubator, and all of them look the same except for 2. The 2nd and 3rd pics are how most of them look. Then I have 2 eggs that look like the first pic.. still lots of space and veins, while the others are already pretty dark (but still have veins).

They are all moving and seem healthy though.

I have had eggs similar to that, where some look more full than others. I think it's just from the position the ducklings are in at the time, and their placement in the incubator might also affect how quickly they grow.

Okay, thanks so much for your answer.
