Is this a Yellowfoot?

I wonder how long they will continue to lay them?
I'll incubate any I find for another 3 months or so after the male is gone.

I thought once the egg laying cycle starts with a female, she lays regardless of a male being present or not until too old.
I'm curious how long the eggs will remain fertile after the last copulation.
