Hatching Muskovy duck eggs for the first time

[Oob Child]

On one of the eggs, the dot has turned into a small circle.

Can you take a photo of each of the eggs being candled?

Can you get a picture?

I'll try

I'm not really sure. It looks like it's on day 3 or 4. What day did you say it was on? Remember, the first 24hrs is day zero.

day 0? This one is about 6/7

They all seem behind, like on day 2 or 3

Well, one doesn't have a circle or dot, but it is on day 2 anyways.

I usually see clear veining day 3. For there to be nothing on day 6-7 I don't think it's fertile.

Unless you see a heartbeat or something moving without you moving the egg, then it's viable. That egg doesn't look viable though.
How old was the egg before you put it in the incubator? What temp do you have your incubator at?
