Egg candling methods and apparatus are provided wherein black rot eggs can be identified and removed. A method of identifying live eggs includes illuminating eggs ina carrier with light from a light source; receiving light passing through each egg at a light detector; generating an output signal that corresponds to light received at a light detector for each respective egg; analyzing the output signal for each egg to determine opacity of each egg; removing eggs having an opacity less than a first opacity value; and removing eggs having an opacity greater than a second opacity value that is different from the first opacity value. ® KIPO & WIPO 2008
