Duck Breeding- Help Please!?

[Duckbreeder2020]

Hi! I have two questions for you. I have a ratio of 2 male ducks to 5 females. One doesn’t really breed though, the other is crazy about it. So here are my questions:

1. My duck bred today, when will her eggs be fertile? Will the next egg she lays be fertile? Or do how long do I have to wait for a fertile egg.

2. How long can ducks hold sperm? If I bred ducks how many eggs (estimated) should be fertile before they need to breed to make for fertile eggs again.

I think if there is an egg in development it won't be fertile but the next will. I think she should be fertile for about 2 weeks. That's assuming the mating was successful.
