Ancona ducks first time laying eggs!

[Goat Lover 3]

My Ancona duck (hen) made a nest in the corner of the coop that I put them in at night. Lately, she has been laying an egg a day starting August 8th. Today she laid her 4th egg! How many eggs will she lay and when will she start sitting on them?? Also, when will the eggs hatch?

Here are some pictures of her nest and her first 2 eggs!

Thanks,
