Is this egg fertile?

[matthewrbo]

the egg attached has a darker spot in the egg visible when candling. Does this mean that the is is fertile and is starting to develop?

Looks like the yolk. Has it been under a broody or in an incubator? If yes, how many days?

It has been in an incubator 3 days

I would say wait 3 more days, them update.
You should see a decent amount of veins by that day.
I have quite a few years of candling under my belt, and sometimes I candle on day 3 or 4, and I'm still not sure it's fertile. Lol.

I also don't candle until day 7. Pro tip- cut a hole in a piece of cardboard about the size of a penny. Put the egg in the hole and shine your light up through the bottom- the comparative darkness provided by the cardboard makes things much more apparent.
