People from the hatchery typically use a process called cand to find eggs. Candling involves shining a bright light through the eggshell to see the interior and assess the quality of the egg, including whether it is fertile and if there is any visible damage. This process is usually done by trained technicians using specialized cand equipment. Candling can also be done manually by holding the egg up to a bright light source, but this method is less accurate and is typically only used for small scale operations.
