Can you tell if egg is fertile by candling?

I wanted to know because I dont always want to FLIPPING open them and waste them!!!

With lighter eggs you should be able to with a strong light, but the darker the eggs get, the harder it will be.

Do you mean before you incubate them? In that case no, it's not possible to tell without opening them and looking for the bullseye.

Only way to tell if an egg is fertile without incubation is to crack them open, sorry. The candeler won't be able to see the target, it will only make any growth show up like veins etc.
