Candling quail eggs

[Nathanya]

I just put some quail eggs I got from my own flock that have been breeding a lot. They have been incubatin for a week now and I candled them. Some look like they have a dark spot in the egg and others I can't tell. I was wondering if they are fertile or not I would really like to see some pictures if anybody has some it would help a lot.

If you have new fresh egg, just candle a few so you can see the different. The fertilized egg will be darker at 7 days.

Ok I wil try that but I stil won't know if they are living and fertile inside the egg
