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.
“Hatching & Brooding Your Own Chicks” by poultry authority Gail Damerow is the definitive guide to hatching healthy baby chickens, as well as ducklings, goslings, turkey poults, and guinea keets. Damerow addresses every possible challenge of the process: selecting a breed, finding the best incubator, ensuring proper set-up and sanitary conditions, understanding embryo development, and feeding and caring for newborn chicks in a brooder.
