How To Keep A Bird Egg Warm: A Step-By-Step Guide

When a mother bird is scared away from her nest or becomes injured, her eggs may face exposure and chill. Keeping abandoned eggs warm is crucial for embryonic development and hatching success. With a few key techniques, you can provide life-saving warmth to orphaned eggs before a wildlife rehabilitator can take over care.

If you’re short on time, here are the key steps: Create an incubator with a heat source set to 99-102°F. Add insulation like tissues or cloth. Turn the eggs gently at least 3 times per day. Maintain high humidity. Handle eggs carefully and minimize temperature fluctuations.

Creating a DIY Incubator

If you find yourself needing to keep a bird egg warm, creating a DIY incubator can be a practical and effective solution. While professional incubators are available on the market, making your own can save you money and provide a safe environment for the egg to hatch.

Here are a few options to consider:

Options like warm water bottles

One option for keeping a bird egg warm is by using warm water bottles. Simply fill a bottle with warm water, wrap it in a soft cloth, and place it near the egg. The heat from the bottle will provide a consistent and gentle warmth to the egg.

Heating pads on low settings

Another option is to use heating pads on low settings. Place a heating pad in a safe and stable position near the egg, making sure to set it on the lowest heat setting available. This method allows for controlled and regulated heat distribution, mimicking the warmth provided by the parent bird.

Directing a lamp toward the eggs

Directing a lamp toward the eggs can also help maintain the necessary warmth. Position a desk lamp or a heat lamp near the eggs, ensuring that the light is not too close to avoid overheating. The heat emitted from the lamp will create a suitable environment for the egg to develop and hatch.

It’s important to monitor the temperature regularly to ensure it remains within the appropriate range for incubation. A reliable thermometer can be used to measure the temperature inside the DIY incubator.

Remember, creating a DIY incubator is a temporary solution and should only be used when absolutely necessary. If possible, it is best to return the egg to its natural habitat or seek professional help from a wildlife rehabilitation center.

These organizations have the necessary expertise and equipment to provide optimal care for the egg.

Insulating the Eggs

When it comes to keeping bird eggs warm, insulation is key. Insulating the eggs helps maintain a stable temperature and protects them from external elements. Here are some effective ways to insulate bird eggs:

Surrounding with soft fabrics

One method of insulating bird eggs is by surrounding them with soft fabrics. This can include materials such as feathers, moss, or even fur. These natural materials provide excellent insulation and help regulate the temperature inside the nest.

By gently adding a layer of soft fabric around the eggs, birds create a cozy environment that helps retain heat and protect the eggs from sudden temperature changes. It’s important to note that using artificial materials like cotton balls or synthetic fabrics may not provide the same level of insulation as natural materials.

Using materials like tissues or paper towels

Another way to insulate bird eggs is by using materials like tissues or paper towels. These lightweight materials can be easily arranged around the eggs to create a protective barrier. They help retain heat and prevent drafts from reaching the eggs.

When using tissues or paper towels, it’s essential to choose unscented and non-toxic options. Birds have a sensitive sense of smell, and scented products may deter them from returning to the nest.

Creating walls around the nest

Birds also utilize their natural instincts to create walls around the nest, further insulating the eggs. They may use mud, twigs, or other materials to build a sturdy structure that shields the eggs from wind and temperature fluctuations.

By creating walls around the nest, birds add an extra layer of insulation and protection. It helps maintain a stable microclimate within the nest, ensuring the eggs stay warm and safe.

Remember, when observing bird eggs or nests, it’s important to maintain a respectful distance and avoid disturbing them. Bird eggs are delicate, and any interference can cause harm to the eggs or disrupt the nesting process.

Maintaining Proper Temperature

When it comes to keeping a bird egg warm, maintaining the proper temperature is crucial for the egg’s development and hatching success. The ideal temperature range for most bird eggs is between 99-102°F (37-39°C).

This temperature range mimics the natural conditions in which the eggs would be incubated by the parent birds.

Check with a thermometer

It is important to regularly monitor the temperature inside the incubator to ensure it remains within the ideal range. Using a reliable thermometer designed for egg incubation is highly recommended. Place the thermometer at the same height as the eggs and make sure it is accurate.

This will help you maintain the right temperature consistently throughout the incubation period.

Pro tip: If you don’t have a specialized thermometer, you can use a medical thermometer to measure the temperature. Just make sure to clean it thoroughly before and after use.

Make adjustments as needed

If the temperature inside the incubator falls below or rises above the ideal range, it is essential to make the necessary adjustments promptly. Small changes in temperature can have a significant impact on the development of the embryo inside the egg.

Pro tip: To increase the temperature, you can slightly raise the heat source or adjust the thermostat settings. To lower the temperature, you can try placing a cool, damp cloth or sponge inside the incubator or adjust the thermostat accordingly.

Remember, maintaining a consistent and appropriate temperature is crucial for the successful incubation of bird eggs. By regularly monitoring the temperature and making adjustments as needed, you can increase the chances of healthy embryo development and successful hatching.

Turning the Eggs

Turning bird eggs is an important step in the incubation process. It helps to ensure that the embryos develop properly and hatch successfully. Here are some key points to keep in mind when turning the eggs:

Gently rotate at least 3 times per day

It is recommended to turn the eggs gently at least three times a day. This helps to distribute the heat evenly and prevents hot spots from forming. Remember, gentle is the key here, as excessive force can harm the developing embryos.

Prevents embryo from sticking to shell

Turning the eggs also prevents the embryo from sticking to the inside of the shell. When the eggs are not turned, the developing embryo can adhere to the inner membrane, making it difficult for the bird to break free during hatching.

By turning the eggs regularly, you can minimize the chances of this happening and ensure a successful hatch.

Helps maturation and positioning

Regularly turning the eggs also helps with the maturation and positioning of the embryos. By gently rotating the eggs, you are giving the embryos a chance to properly develop and position themselves inside the egg. This is important for their overall growth and health.

It’s important to note that different bird species may have specific requirements when it comes to turning eggs. It’s always a good idea to do some research and consult reliable sources, such as Audubon or All About Birds, for species-specific information.

Increasing Humidity

Crucial in the last days before hatching

During the final days before hatching, maintaining the right humidity level is crucial for the survival of the bird embryo. High humidity helps prevent the egg from drying out, which can lead to the death of the developing bird.

Research has shown that eggs with inadequate humidity levels have a lower hatch rate, so it is important to pay close attention to this aspect.

Use a humidifier or damp cloths

There are several ways to increase humidity inside the incubator. One effective method is to use a humidifier specifically designed for incubation purposes. These devices release a fine mist of water vapor, creating the perfect environment for the eggs.

Alternatively, you can place damp cloths or sponges inside the incubator to increase humidity. Just make sure to monitor the humidity levels regularly to ensure they stay within the optimal range.

75-80% humidity is optimal

The optimal humidity range for bird eggs in the final days before hatching is usually between 75-80%. At this level, the eggs are provided with enough moisture to prevent them from drying out, while still allowing for proper gas exchange.

It is important to note that different bird species may have slightly different humidity requirements, so it’s always best to consult species-specific guidelines or recommendations from reputable sources such as Backyard Chickens or Cornell Lab of Ornithology.


With some DIY equipment and attentive care, you can successfully incubate abandoned bird eggs until they can be taken to a wildlife rehabilitator. Focus on maintaining a consistent temperature and humidity while gently turning the eggs multiple times per day.

Handling eggs with care while minimizing fluctuations will give orphaned bird embryos their best chance at survival.
