Bearded dragons are popular pets for reptile enthusiasts, and female bearded dragons can lay anywhere between 11 and 35 eggs per clutch, up to four times over several months. Caring for these eggs can be tedious and requires careful monitoring of humidity and temperature to prevent mould. One important step in this process is candling, which is the practice of using a low-wattage flashlight to check for signs of a growing embryo. This is how to candle bearded dragon eggs.

| What is candling? | Candling is a method to determine whether bearded dragon eggs are fertile. |
| How to candle | Use an extremely low-watt flashlight to check for vein clusters or a dark circle, indicating a growing baby dragon. |
| When to candle | Wait at least a few days after an egg is laid before candling. Do not disturb the bearded dragon while it is laying. |

Candling technique: use a low-wattage flashlight to check for embryo growth
Candling is a simple but important technique that allows breeders to check if bearded dragon eggs are fertile and monitor embryo development. It involves using a bright light source, such as a small, high-intensity LED flashlight, to see inside the egg without opening it.
To candle bearded dragon eggs effectively, follow these steps:
Prepare the Environment:
Create a dark room to help see through the eggs more clearly. Turn off the lights and close any windows or doors to prevent external light from interfering with the process.
Handle the Eggs with Care:
Gently pick up each egg, being careful not to rotate or shake it. Avoid direct contact between the light source and the egg. Place the flashlight close to the egg, shining the light through it from one side to the other, with the light facing you and filtered by the egg.
Observe for Embryo Growth:
Look for signs of embryo development, including the presence of tiny red blood vessels or vein clusters, which indicate a fertilised egg. You may also notice a dark spot, which is the embryo itself. Infertile eggs, on the other hand, will remain clear, cloudy, or display a yellow yolk floating inside.
Monitor Regularly:
Initial candling can be done 7-10 days after laying, followed by regular monitoring every one to two weeks. This allows you to track the embryo's growth and ensure proper development.
Act on Any Issues:
If you notice any issues during candling, such as infertility or poor incubation conditions, take prompt action. Adjust the incubation conditions, ensuring optimal temperature and humidity levels. Consult a reptile veterinarian for persistent development issues and always prioritise the health and safety of the eggs.
By following these steps and using a low-wattage flashlight, you can effectively candle bearded dragon eggs to monitor embryo growth and create the best conditions for healthy hatching.

Incubation: maintain 75% humidity and 80-85°F to prevent mould
Maintaining the right temperature and humidity levels is critical for successfully incubating bearded dragon eggs. The ideal temperature for the eggs is 80-85°F, and the humidity should be kept at 75%.
To achieve the desired temperature, you can use heat lights or an under-tank heater. It's important to avoid using a glass lid for the enclosure, as this can increase humidity to unacceptable levels. Instead, ensure that the enclosure has proper ventilation by using a screen top. Maintaining the correct temperatures on the hot and cool sides of the enclosure can also help regulate humidity.
To monitor the humidity levels, it is recommended to use a digital hygrometer. You can also visually inspect the eggs for any signs of mould. While misting the enclosure can help increase humidity, it should be done sparingly as it can contribute to unsanitary conditions, leading to fungal and bacterial infections. Therefore, it is crucial to maintain humidity within the recommended range of 70% to 80% during the incubation period.
To maintain the desired temperature and humidity levels, you can make adjustments to the enclosure setup. For example, placing a water dish on the cool side of the enclosure can help reduce evaporation and lower humidity. Additionally, live plants should be placed on the cool side, as humidity levels near the basking area will be lower due to the heat lamp. By understanding the relationship between temperature and humidity, you can create an optimal environment for incubating bearded dragon eggs.

Handling: wait a few days before handling eggs to avoid embryo detachment
When a female bearded dragon is carrying eggs, she is referred to as gravid. Gravid female bearded dragons may become lethargic, sleep a lot, and spend more time basking under the heat lamp. Their bellies will also appear larger than usual.
Once the eggs are laid, it is important to wait a few days before handling them to avoid embryo detachment. This is because moving the egg too soon after it is laid could cause the embryo to detach from the egg wall and die. Therefore, it is recommended to wait at least a few days after an egg is laid before candling or rotating it.
Candling is a process of shining a flashlight through the egg to check for a pinkish embryo inside, indicating that the egg is fertile. It is important to use an extremely low-watt flashlight to avoid causing a sudden rise in temperature in the egg, which could harm the fragile embryo.
Bearded dragon eggs should be incubated at around 80-85 degrees Fahrenheit, with a humidity level of about 75%. It is important to use a digital thermometer to ensure that the temperature stays within the optimal range, as sustained temperatures above 90 degrees can quickly kill developing embryos.
Overall, it is crucial to handle bearded dragon eggs with care and patience to give the embryos the best chance of survival.

Timing: fertile eggs take 40-90 days to hatch; infertile eggs won't hatch
The timing of a bearded dragon egg hatching depends on several factors, including temperature, humidity, and whether the egg is fertile. Typically, a fertile bearded dragon egg will take between 50 and 80 days to hatch, with 60 days being the average. During the incubation period, it is crucial to maintain the right temperature and humidity levels. The ideal temperature range is between 80 and 85 degrees Fahrenheit, and humidity should be maintained at around 75%.
To ensure successful hatching, it is recommended to use an incubator to control these environmental factors. The eggs should be placed on a substrate that is moist but not wet, and they should be spaced evenly with small dents made in the substrate to prevent rolling. The incubator temperature should be set to 29°C (84°F) to achieve the desired hatching time frame.
It is important to note that fertile eggs should not be handled too much as it could damage the growing embryo inside. Additionally, the eggs should not be moved around more than necessary. If you do not have an incubator, you can use a thermometer and hygrometer placed in the nest with the eggs and wait patiently for hatching.
Infertile eggs will never hatch and can be disposed of at any time. To determine if an egg is infertile, hold a flashlight up to it and look for the presence or absence of a pinkish embryo. If there is no embryo visible, the egg is likely infertile.

Signs of life: vein clusters, a dark circle, or a reddish spot indicate growth
When candling a bearded dragon egg, look for a dark circle or vein clusters, which indicate a possible baby dragon growing inside. This process involves holding a low-wattage flashlight up to the egg to allow you to see inside without moving the egg itself. You may also see a reddish spot, which is a sign of a growing embryo.
Candling is a useful way to check on the growth of a baby bearded dragon inside an egg. It is also a good way to check if an egg is fertile. Infertile eggs will not have any veins or embryos visible inside them. They will also be dented and have a dull yellow or orange tinge, rather than appearing full and white-tinged.
It is important to wait at least a few days after an egg is laid before candling it, as moving the egg too early could cause the embryo to detach from the egg wall and die. Bearded dragon eggs are very delicate, and care should be taken not to rotate them.
To ensure the eggs remain healthy, it is important to maintain the correct humidity and temperature. The ideal humidity for incubating bearded dragon eggs is around 75%, and the temperature should be kept constantly at 80-85°F.
