With N.A. milks, my experience has been that females come into prime production around 10 years with larger eggs, larger clutches and more predictable breeding.
I have a couple N.A. males that are at least 15 years old and still give the girls a run.
I feel it's a myth that females are prime breeders only in the 4-7 year range. Maybe some are worn out and stressed, but that's a different matter.
