How to tell if a egg is fertile without cracking it open?

[Mutchi]

Can someone tell me if any of my eggs are fertile by these candling pics? And pls tell me how?

You can tell by incubating. If layers are with a mature rooster, chances are it is fertile.

The only way I know of is to open the egg and look for the blastoderm/disc or incubate.
