Discover why birds cannot lay fertilized eggs without mating and how the fertilization process works in birds.

Birds cannot lay fertilized eggs without mating. For an egg to be fertilized, sperm from a male bird must merge with an ovum from a female bird. This fertilization process happens internally after successful mating. Thus, without mating, any egg a female bird lays will be infertile and will not develop into a chick.
