Candling an egg just means that you hold a bright light, or candle back in the day, up to the egg and see if anything looks like blood vessels or the shadow that might resemble an embryo, you will know if you see it. A fertilized egg is called a "winner." If you discover your fertilized eggs has stopped developing, that is called a "quitter." If you have an unfertilized egg, that is called a "yolker."
