Determining whether eggs are fertilized is a crucial step in animal breeding, particularly in poultry farming. Fertile eggs have the potential to develop into embryos and hatch into live chicks, while infertile eggs will not. There are several methods to check if eggs are fertilized, each with its advantages and disadvantages.
One common method is called candling. This involves holding the egg up to a bright light and observing the contents inside. Fertilized eggs will have a visible embryo, which appears as a dark spot or a network of blood vessels. Infertile eggs, on the other hand, will remain clear or have a uniform yellow color.
