  2. Do wild birds lay unfertilized eggs? Most wild bird species lay eggs primarily for reproduction and generally do not lay unfertilized eggs regularly since fertilization is required for viable offspring.
  3. What is the difference between fertilized and unfertilized eggs in birds? A fertilized bird egg contains genetic material from both the male and female and can develop into a chick, while an unfertilized egg lacks male genetic input and will not develop.
