How to Candle Eggs

By “egg candling,” or placing a bright light behind your eggs, you can determine the age of your eggs and find imperfections such as hairline cracks and double yolks that prevent the eggs from being good candidates for hatching. Learn how to candle eggs on your homestead.

Cracks in the shell that may not be readily visible will appear during candling as white veins and/or spiderweb-like shapes.
