You can "candle" them. Hold the egg in front of a light bulb and look for the yolk. It will be in one end or the other. If that's all you see, it is not fertile. If there is more dark area in the egg than just the end, it probably is fertile. It takes a while for the chick to develop, so let them sit for a while before you do this.
all you have to do is hold the egg up to the sun or get a LED light and shine the light through and if it has red in it, it means its fertalised. you can also see a shadow in the egg
well it ornge and big

There is nothing different if you are talking about a live egg as there is a chick growing in side of it. a fertile egg is when the daddy rooster make the egg fertile
I guess you would candle it just like any other egg. You put the egg on a focused beam of light in a dark room and if the light won't go through and the egg doesn't light up, it's fertile.
I have had good luck holding the egg up to bright flashlight - if it is not fertile, the light will make the egg look transluscent. If it is fertile, the light will be blocked. Once you see it for yourself, you'll see that it's easy to do.

After day 5 of incubation you can candle the egg to see shadowy changes within the egg. There are no outward indicators of fertility with chicken eggs. Candling eggs means to shine a bright light into the end of the egg and observe the development of the embryo within. A non fertile egg will show no shadows within the shell.
