How old are guineas when they start laying fertile eggs?

[Love my babies]

I talked to the people who I got my babies from, they have been raising them for years now and usually hatch them in incubators, they told me that it happens to them most every fall but since they bring them in to put them in incubator it never a problem.so it looks like im not going to get to put up my incubator like I thought I was going to get too.

I got my first guineas last year as two-day-old keets in June (so about the same age last Sept. as yours are now) and we found the first nest in early June.
