How to tell if an egg is fertile?

[Owenp_2]

Hey everyone my rooster has been mating with one of my hens a lot recently and I was wondering how to candel an egg because what I find online just doesn't work. So can you please show me what to look for in a brown and a blue egg?
Thanks,
Owen

I reccomend you incubate the eggs for 6-8 days, then you'll find this guide helpful:

A fertile living egg, will have a red tint when candled, and you can see veins after 5-7 days. An infertile egg will have a white and yellow tint, with no veins. It will look like this, the orange part of the egg, is no the embryo, it is the yolk- ⬇

This is fertile, red tint, veins and embryo seen on day 4-7 ⬇

Of course, you can only tell if it is infertile on the 5th-7th day.

What does a fertile egg look like on the first day though?

You wont see much of anything on the first day, it will look normal, white with a yellow yolk. The article that was linked above explains it well

You can't tell if an egg is fertile or not unless you incubate if for several days.
They're likely fertile if she is mated by him regularly.
