Incubation for Mascovy ducks

[Coco Chanel]

I have a female Mascovy who keeps laying eggs and I'm not sure if I have a male or not. I have 3 ducks and not sure what the other 2 are. I was wondering from the time she lays the egg until the time they hatch, how long until you could see if there was a chick in the egg. I know you can shine a light to the shell and you can see through them and it looks like nothing is inside, how long before you can see if something is in there? Thank you.
