I had a fully formed silkie bantam in the egg but it never broke into the air sac nor pipped.. what could have went wrong?

 

[Becci]

1. Sign: Not pipped. Full-term embryo, large yolk sac; yolk sac may not be fully enclosed by abdominal wall, may have residual albumen. Causes:
   1. Inadequate turning, resulting in decreased embryonic membrane development and nutrient absorption.
   2. Humidity too high during incubation or after transfer.
   3. Incubator temperature too low.
   4. Hatcher temperature too high.
   5. Eggs chilled (e.g., at transfer).
   6. Nutritional deficiencies.
   7. Heredity.
   8. Embryological development accident.
   9. Breeder diseases.
   10. Inadequate ventilation.
   11. Prolonged egg storage.
