Once all the necessary materials for the incubator are gathered, the next step is to set up the environment inside. A hygrometer is crucial in order to measure the humidity inside the incubator.

It is important to ensure that the humidity is kept at an optimal level for the eggs to hatch properly. Furthermore, the table below provides an overview of the hygrometer setup and settings and the corresponding humidity levels for the incubator.

Hygrometer Setup & SettingsHumidity Levels (%)
High Humidity85-100
Medium Humidity70-84
Low HumidityBelow 70

When setting up the hygrometer, it is important to note the following:

  • Position the hygrometer in the center of the incubator for the most accurate readings.
  • Ensure that the hygrometer is not touching any walls inside the incubator.
  • Make sure that the hygrometer is not placed near any heat sources such as lamps inside the incubator.

Once the hygrometer is set up, the humidity levels can be monitored and regulated to ensure that the eggs have the best environment to hatch in.

Substrate (Vermiculite or Sand)

Transitioning from the topic of necessary supplies, the next item to consider is the substrate. After a hygrometer, the substrate is the most important supply for an incubator. Substrate, usually in the form of vermiculite or sand, is necessary to create the perfect environment for the eggs.

When choosing a substrate, it is important to select one that is absorbent and can hold the moisture of the incubator. Vermiculite is a great choice for this, as it is made of tiny mineral particles that are able to hold the necessary moisture. Vermiculite also has excellent aeration, allowing the eggs to breathe.

Table 1: Pros and Cons of Vermiculite and Sand as Substrate

VermiculiteAeration, absorbent, holds moisturePrice, difficult to clean
SandInexpensive, easy to cleanDoes not hold moisture, aeration is limited

Overall, vermiculite is the ideal choice for an incubator, as it has the ability to hold moisture and provide aeration:

  • Aeration:
    • Vermiculite provides excellent aeration for the eggs.
    • Sand does not provide the same level of aeration as vermiculite.
  • Moisture:
    • Vermiculite is able to hold moisture, allowing the incubator to stay humid.
    • Sand does not hold moisture as well as vermiculite.

In conclusion, vermiculite is the best substrate for an incubator. Providing aeration and moisture is an essential supply for ensuring the successful hatching of Bearded Dragon eggs.

When it comes to eggs, the type of eggs you use is essential. Bearded dragon eggs should be collected from the female, as soon as they are laid. If not, they will start to rot quickly.

It is important to know certain elements about the eggs before handling them, such as:

  • Size
  • Weight
  • Number of eggs produced by the female
  • Eggs’ firmness
  • Shell color

It is also important to note that, if the eggs are laid in the wild, they must be brought to a safe and clean environment as soon as possible. And, if the eggs are collected from a captive female, they must be disinfected to prevent any contamination.

Below is a table that summarizes the essential elements to consider when handling Bearded dragon eggs:

SizeThe size of a single egg should range from 0.75 to 1 inch (2-2.5 cm) in diameter.
WeightA single egg should weigh about 3 to 4 grams.
Number of eggsFemales can lay up to 25 eggs, but it is more common to find clutches of 5-10 eggs.
Eggs’ firmnessThe eggs should be firm, not too hard or too soft.
Shell colourThe shells should be a creamy white colour with some dark spots.

Finally, it is important to remember that, if the eggs are handled carefully, they should be kept in an incubator for about two months. This will ensure that the eggs are in optimal condition for hatching.

Prepare the Incubator Container

Now that you have all the necessary supplies, it’s time to prepare the incubator container. This is an important step to ensure successful incubation. To begin, you will need a suitable container for the eggs.

Ideally, this container should have a lid that fits securely and is made of a material that will not absorb moisture. The container should also be large enough to hold the eggs in a single layer without crowding them. Additionally, the container should have adequate ventilation to ensure proper air circulation.

Once you have a suitable container, it’s time to add substrate. The substrate acts as a protective layer between your eggs and the bottom of the container, so it’s important to choose one that’s safe for your eggs.

It should be made of a material that won’t hold too much moisture, such as vermiculite or perlite. Additionally, it should be deep enough to provide coverage for the eggs without burying them. After adding the substrate, it should be slightly moistened to help maintain the necessary level of humidity.

Now that the container is ready, it’s time to add the eggs. Carefully place the eggs in the container, being careful not to roll or move them. Make sure that they are evenly spaced to ensure that they have enough room to develop properly. Once the eggs are in place, the incubator is ready for use.

Prepare the Vermiculite

Now that the incubator container is prepared, it’s time to prepare the vermiculite. Vermiculite is a lightweight mineral that is used to provide warmth, insulation, and moisture to incubator eggs. It is an essential component of the incubation process and must be prepared properly to ensure successful hatching.

To prepare the vermiculite, mix it with a solution of lukewarm water and baking soda. Use a ratio of one part baking soda to three parts water, and stir the mix until the baking soda is completely dissolved.

Add the vermiculite and mix until it is evenly moistened. Allow the mixture to sit for a few minutes to allow the vermiculite to absorb the moisture. Once the vermiculite is damp, it is ready to be added to the incubator container.

It is important to use the correct amount of vermiculite for the incubator container. Too much vermiculite will create a moist environment that can be detrimental to the incubation process, while too little vermiculite can lead to a dry environment that can also be harmful to the eggs.

For best results, use about two cups of vermiculite per incubator container.

Place the Bearded Dragon Eggs in the Vermiculite

Now that you have prepared the vermiculite, it’s time to place the bearded dragon eggs in it. Ensuring the eggs are properly incubated is vital to the survival of the baby dragons. The next steps will provide the ideal environment for the eggs to hatch.

The first step is to create a shallow indentation in the vermiculite with your hands. Make sure the indent is shallow because the eggs need to be in contact with the vermiculite, so they can maintain the correct temperature. Once you have created the indent, lightly press the eggs into the vermiculite.

The second step is to cover the eggs with at least 1/3 of the vermiculite, making sure not to press too hard. Covering the eggs is important because it helps to keep the eggs at the ideal temperature and also prevents them from drying out.

Once the eggs are covered, place the container with the eggs and vermiculite in a warm, secure area where they won’t be disturbed.

You have now successfully placed the bearded dragon eggs in the vermiculite. The eggs will now begin to hatch after around 60-90 days. With the right environment and proper care, you are sure to have a new generation of baby dragons soon!

Maintain Incubator Conditions

Temperature is an important factor to consider when operating an incubator. A consistent temperature is essential for successful incubation, so it is important to monitor and adjust the temperature regularly.

Humidity is also a key factor for successful incubation. High humidity levels create a better environment for the eggs to grow and develop. Ventilation is also important to ensure adequate airflow and to reduce the risk of any health issues due to stagnant air.


After carefully placing the Bearded Dragon eggs in the vermiculite, it is essential to maintain the incubator conditions for the eggs to hatch. Temperature is one of the most important factors to consider when incubating Bearded Dragon eggs.

The temperature should be kept between 88-93°F, with variations of no more than 1°F between day and night for ideal hatching.

To keep the temperature consistent, it is important to use a digital thermometer to monitor the temperature and use a heating pad or reptile heat lamp to keep the incubator warm.

Temp (°F)Time of DayHeat Source
88-93Day/NightHeat Pad/Lamp
87-92NightHeat Pad/Lamp
86-90DayHeat Lamp

It is important to monitor temperature constantly with a digital thermometer to ensure the eggs are kept in an ideal environment. In addition, it is important to ensure the temperature of the incubator does not reach over 93°F, as this can cause the eggs to overheat and the embryos to be killed.

If the temperature of the incubator falls below 86°F, then the embryos will not develop properly. It is important to adjust the heat source accordingly in order to maintain the optimal temperature.


After placing the eggs in the vermiculite, the next step is to maintain the incubator conditions. One of the most important conditions to keep an eye on is humidity.

Humidity RangeIdeal Humidity

Humidity levels are vital in keeping eggs alive in incubation. Creating the right balance of humidity, it can make or break the developing eggs.

Too high of a humidity level can increase the chance of eggs growing fungus, and too low of a humidity level can cause the embryos inside to dry up and die. Therefore, it is imperative to monitor the humidity levels regularly and stay within the ideal range.


Once you have placed the eggs in the vermiculite, it is important to maintain the right conditions in the incubator. One of the most important factors to consider is ventilation. Having adequate air circulation is essential to ensure that the eggs receive enough oxygen and to prevent the build-up of high levels of carbon dioxide.

Adequate AirflowIneffective Airflow
Prevents stagnationLeads to stagnation
Reduces temperature fluctuationsIncreases temperature fluctuations
Oxygenates the incubatorLeads to a lack of oxygen

It is important to ensure that the incubator is consistently ventilated so that the environment does not become too stagnant. This can be done by using vents, air pumps, or fans.

Additionally, the incubator should be kept in a room with a constant temperature, as any sudden temperature changes can cause the eggs to develop abnormally or be unable to hatch.


Creating an incubator for Bearded Dragon eggs is a relatively straightforward process. All that is required are the necessary supplies, the correct incubator conditions, and a bit of patience.

With the right supplies and conditions, you should have no problem creating an incubator that will ensure your Bearded Dragon eggs hatch safely and successfully. With the right incubator, you will be sure to have a successful hatching of your Bearded Dragon eggs, which can then be enjoyed for many years to come.
