It does happen in non poultry birds even wild ones. The reason it doesn't really happen in the wild is most wild birds will never be in the position to be unfertilized because they will most likely mate and lay fertilized eggs. Pet birds like parrots and cockatiels can lay unfertilized eggs and can be a problem and can lead to malnutrition.
