When will my eggs be fertile?

I just bought a gander for my girls and they instantly started laying again? I'm sure those aren't fertile...but how long until they are?? Thanks.

Hi there,
The only way to test if the eggs are fertile,
Is to crack one open and find a bulls eye.
If it doesn't have one then they are infertile.
I would say it will take about 1 week - 2 weeks ,
For the eggs to be fertile.
Goodluck,
Fionn.
