Is this egg fertile?

[FlockO5ive]

I recently had to rehome our Ameracauna rooster (we can't have them) but I kept him as long as I could to get some babies. I have never seen him mate with my Ameracauna but when I checked an egg today I saw this. Is it fertile? If so I'm gonna save a clutch of her eggs to incubate.

Looks like a fertile egg. A general rule of thumb is 2 weeks of high fertility, 1 week of moderate fertility, and 1 week of occasional fertility after a rooster has been removed. Understand that this all depends upon the fertility of the rooster involved.

The light white target on the yolk means fertile
