Lockdown is a critical phase in egg incubation, but many overlook the importance of humidity control. Too high or low humidity can ruin your hatch. In this post, we'll explain what incubation lockdown is and why proper humidity is crucial. You'll also learn practical tips to lower humidity for a successful hatch.
As you approach the final days of incubation, humidity levels need to rise. During lockdown, the humidity should be increased to soften the eggshells and help chicks hatch. A stable, higher humidity level makes it easier for chicks to break through their shells. If humidity drops too low, the eggs may dry out, making hatching much harder.
Humidity plays a crucial role in egg development, especially during the last few days. If humidity is too low, the chick can get "shrink-wrapped," where the inner membrane dries out and sticks to the chick. This makes it almost impossible for the chick to break free. Maintaining the right humidity prevents these issues and supports healthy chick development.
Different types of eggs have specific humidity needs during lockdown:
Chicken Eggs: The ideal humidity is between 65%-75% during the final days.
Duck and Exotic Bird Eggs: These require even higher humidity, especially in the last stages of incubation.
Reptile Eggs: Humidity for reptiles usually needs to be between 60%-70%, depending on the species.
Ensuring the correct humidity range is critical for successful hatching across all egg types.
Excessive humidity can be spotted through several visual cues inside the incubator:
Condensation: If you notice water droplets forming on the walls or windows of the incubator, it's a sign that humidity is too high.
Water Droplets on Eggs: Water on the eggshells means there's too much moisture in the air.
Sweaty or Damp Eggshells: If eggs feel damp or sweaty to the touch, the humidity levels are likely above the ideal range.
High humidity can also affect the eggs' development in subtle ways. Keep an eye out for:
Difficulty in Hatching: If chicks struggle to break free from their shells or hatch later than expected, high humidity could be to blame.
Lower Hatch Rate: If fewer eggs hatch than usual, excessive moisture might be interfering with the egg development process.
Too much humidity during the final stages of incubation can lead to serious problems, such as:
Possible Deformities in Chicks: High moisture levels can cause the chick to develop abnormally.
Mold and Bacteria Growth: Excess moisture creates an ideal environment for mold and bacteria, which can harm embryos and reduce hatch rates.
Being mindful of these signs can help you adjust humidity levels before they cause issues.
One of the easiest ways to lower humidity is by adjusting the water levels:
Reducing Water Levels: Lower the amount of water in the trays or reservoirs. This reduces the moisture in the air.
Removing Unnecessary Water Trays: If your incubator has multiple water trays, remove those not essential for maintaining temperature.
The Role of Water Surface Area: More water surface area means more evaporation, which increases humidity. By reducing the surface area of the water, you can control moisture more effectively.
Using Sponges: Sponges can absorb moisture without raising the temperature. Place them in the incubator to manage humidity without affecting the overall temperature.
Improved airflow helps regulate humidity by allowing moisture to escape:
Opening Vents: If your incubator has air vents, open them slightly. This lets excess moisture escape and reduces humidity.
Using a Small Fan: If your incubator lacks sufficient airflow, adding a small fan can increase air circulation and reduce moisture buildup.
Desiccants are materials that absorb moisture and can be very effective:
Silica Gel Packs: Place silica gel packs inside the incubator to absorb moisture from the air.
Other Desiccants: Materials like activated charcoal or calcium chloride can also absorb excess moisture. Just make sure they don’t touch the eggs directly.
To control excessive moisture, you can use towels or sponges strategically:
Positioning Towels: Place dry towels or sponges near the walls, not directly on the eggs. They help absorb moisture from the air.
Regular Replacement of Sponges: Sponges need to be replaced regularly once they absorb enough moisture. If left in too long, they can increase humidity.
By following these practical tips, you can effectively reduce humidity levels without causing harm to your eggs.
If you need to lower humidity quickly, removing excess water from the incubator can help:
Temporarily Removing Water Trays: If humidity is too high, you can remove water trays or reservoirs to reduce moisture levels. Be careful to do this without causing temperature shifts in the incubator.
Monitoring Temperature and Humidity: After removing the water sources, keep a close eye on both temperature and humidity. Make sure the environment remains stable to avoid harming the eggs.
This method should be used cautiously to avoid sudden changes in conditions, which could affect your hatch rates.
One of the biggest mistakes is making sudden changes in humidity levels:
Risks of Sudden Changes: Rapidly dropping humidity can harm egg development. It may cause the chicks to struggle or not hatch properly.
Best Practices for Gradual Adjustments: Instead of big changes, lower the humidity slowly. This gives the eggs time to adjust without stressing the embryos.
Consistent monitoring is key to stable conditions:
Importance of Regular Checks: You can't assume humidity will stay steady. It's important to check it often, especially during lockdown.
Using Tools for Accurate Readings: Digital hygrometers and humidity loggers help you track changes accurately. Set reminders to monitor the levels throughout the day.
Temperature fluctuations can throw off humidity:
How Temperature Affects Humidity: Changes in temperature can cause unexpected changes in humidity, either raising or lowering it.
Maintaining the Right Temperature: For chicken eggs, keep the temperature around 37.5°C (99.5°F). Use an external thermometer to track any fluctuations and adjust accordingly.
Avoiding these common mistakes can help ensure a smoother and more successful hatch.
If you're still struggling with high humidity despite adjustments, here are some steps to take:
Identifying Condensation Issues: Condensation is a clear sign that the humidity is too high. Look for water droplets on the incubator walls or eggs. This could happen if your incubator's humidity control system is malfunctioning.
Fixing the Humidity System: If you notice persistent condensation, check the water levels and vents. Ensure the humidity system is working correctly. If not, you may need to replace faulty parts like the humidifier or thermostat.
If you've tried everything and humidity remains an issue, it might be time to consult an expert:
When to Call for Help: If you can't fix the humidity problem on your own, a technician may be able to assess the incubator and fix any underlying issues.
Professional Tools and Services: Experts can offer specialized tools like humidity loggers or recalibrate your incubator for optimal performance.
Getting professional help ensures you avoid further complications during the critical hatching period.
Lowering humidity during lockdown requires gradual adjustments and consistent monitoring. Use tools like hygrometers to track both humidity and temperature. By maintaining the ideal humidity levels, you ensure healthier embryos and successful hatching. This leads to higher hatch rates and better chick quality, giving you the best chance for a successful hatch. For professional incubators, whether automatic or manual, you can rely on Janoel , We offer well-equipped testing facilities and strong technical support to meet all your incubation needs.
A: Remove or reduce water trays, open vents slightly, or add dry sponges. Avoid changing incubator heat settings.
A: Chicks may get shrink-wrapped in the membrane and fail to hatch. Add warm water or damp sponges to raise humidity slowly.
A: Only if necessary. Opening it drops humidity and temperature fast. If you must, do it quickly and before pipping begins.
