Backyard chicken owners can apply the knowledge of “Dead-In-Shell” to enhance the health and well-being of their flock. Some practical steps to achieve this include:
1. Selecting high-quality eggs: Make sure to source eggs from reputable breeders or suppliers, ensuring that the parental stock is healthy and well-cared for. Choose eggs that have strong shells and are relatively uniform in size.
2. Proper egg handling and storage: Handle eggs carefully to avoid any damages to the shell or the embryo inside. Store them at a constant temperature of around 50-60°F (10-15°C), with a humidity level of 70-80%. Position the eggs with the pointed end downwards, and turn them at least once per day.
3. Creating an optimal incubation environment: Maintain a consistent temperature of 99.5°F (37.5°C) for forced-air incubators or 101.5°F (38.6°C) for still-air incubators. Keep the relative humidity between 40-50% during the first 18 days of incubation, and then increase it to 65-75% at the final stages until hatching. Ensure proper ventilation and frequent egg turning to simulate a natural hatching process.
4. Monitoring egg development: Candle eggs periodically to track the growth of the embryo and identify any potential issues requiring intervention. Address concerns promptly and adjust incubation conditions as needed. Remove any non-viable eggs or deceased embryos to safeguard the remaining healthy ones.
By following these practical guidelines, backyard chicken owners can optimize their hatching process, increase the survival rate, and ensure a thriving and healthy flock.
Tips & Recommendations for Preventing Dead-In-Shell
To ensure optimal chicken care and minimize the “Dead-In-Shell” phenomenon in your flock, follow these practical tips and best practices:
1. Maintain optimal incubation conditions: Keep a consistent temperature and humidity throughout the incubation period. Invest in reliable incubator thermometers and humidity gauges to monitor conditions. Adjust these variables as needed during each phase of incubation.
2. Ventilation and hygiene: Provide proper airflow in the incubator to ensure an adequate oxygen supply and carbon dioxide removal. Clean and disinfect the incubator and its contents before and after each use to prevent bacterial or fungal growth and minimize the risk of contamination.
3. Egg handling: Let eggs settle for at least 24 hours before incubation, allowing the air cell to stabilize. To prevent contamination, wash your hands before handling the eggs and avoid touching the incubator too often during the incubation period.
- 4. Choose the right incubator: Select an incubator of appropriate size and functionality for the number of eggs you’re hatching. Automated egg turners and accurate temperature and humidity controls can make a significant difference in the success rate of hatching.
- 5. Candling: Use a candler to monitor embryo development and discard any eggs that show signs of contamination or no growth by the midpoint of the incubation period. Remove any eggs with blood rings or other signs of embryonic death.
- 6. Learn from experience: Keep a record of your hatching experiences, noting factors like temperature, humidity, egg source, and other conditions. Use this information to identify patterns and make improvements for future hatching attempts.
- 7. Seek advice or assistance: If you are struggling with a high rate of “Dead-In-Shell” eggs, reach out to experienced poultry breeders or join a poultry community online to discuss potential solutions and gain insights into the issue.
