- Turning eggs ensures uniform heating for proper development of the embryo inside. By rotating the eggs regularly, the birds prevent overheating or underheating of any specific area, promoting consistent warmth throughout the egg.
2. Prevents Embryo Adhesion to the Shell:
- As the egg develops, the embryo can sometimes adhere to the inner shell membrane, which can be fatal if not corrected. Periodically turning the eggs helps prevent this by gently dislodging any attachments.
3. Facilitate Gas Exchange:
- The air sac located at the blunt end of the egg provides oxygen for the developing embryo. Turning the egg allows for proper positioning of the air sac and facilitates adequate gas exchange, ensuring a continuous supply of fresh oxygen.
4. Redistribution of Yolk:
- The yolk is crucial for nourishing the developing embryo. By turning the eggs, birds redistribute the yolk, preventing it from settling at the bottom and ensuring that the embryo has access to essential nutrients throughout its growth.
5. Strengthens the Shell:
- Turning eggs helps strengthen the eggshell by stimulating the inner shell membrane, which produces a protective coating. This reinforced shell improves the chances of survival during incubation and protects the embryo from potential damage.
6. Natural Behavior:
- In nature, birds naturally turn their eggs as part of their incubation behavior. This innate instinct helps ensure optimal conditions for successful egg development and hatching.
