Some quick simple information on when your Bearded Dragon lays eggs whether fertile or infertile.
On average these lizards will have between 16 and 24 eggs in a clutch and they’ll lay multiple clutches depending upon various factors.
If the bearded dragon eggs are infertile then they may only lay one clutch, but if they’re fertile then expect around 6 batches – they’ll normally stop laying eggs as soon as they lay infertile eggs and that depends on how much sperm they’ve stored and how much energy and calcium they have.
Also, be careful to watch out for any symptoms of egg binding in your Bearded Dragons.
Nutrition while laying eggs
Whether laying infertile or fertile eggs, the dragon will need plenty of calcium and energy, if you don’t provide additional calcium supplements, the eggs will use calcium from the dragon’s bones.
Also, all that digging and egg-laying will exhaust the dragon so you’ll want to feed daily with more insects and vegetation – after all this is what the beardie will use to create the eggs. You should find that their appetite substantially increases during this period.
If your lizard should stop eating for more than a couple of days, it’s time to see a vet to get an x-ray and to monitor the condition, if the dragon doesn’t lay the eggs it can become egg bound, where the eggs solidify and bind internally with the dragon causing paralysis and even death. So be sure to keep an eye out for this.
You need around 6 inches at least, 10-12 inches is better, of substrate for the female to dig a burrow in, the best stuff I found is a mixture in equal parts of vermiculite (to retain moisture), play sand, and topsoil.
Add to this some water to ensure it can hold its shape without collapsing and get a big piece of bark to go over the top.
I also found that in the vivarium, the female will tend to prefer to dig a burrow in the warm end, normally under the heat lamp. Although before doing this, she’ll create several test burrows over the course of a few days, so you’ll need deep substrate for all of the viv – I slope it up towards the back to give varying height.
After she’s dug her hole, she’ll lay the eggs in under 30 minutes and then spend a while burying them up again. What you need to do is to carefully remove the soil again and taking note of the position of the egg, transfer them to the incubator keeping them in the same position (more on that later).
If she just laid one set of eggs, you may be able to leave them in the tank, but in a few weeks she is more than likely to dig another burrow for the next clutch and she’ll always choose the same place when in the vivarium, thus ruining the eggs if left in there. Generally, bearded dragons do not care about their eggs.
Infertile Bearded Dragon eggs
These will be yellow and smaller than average. Remove them straight away and throw them out. This also signifies that that’s the end of the egg-laying.
I mention infertile eggs also because lizards will develop eggs anyway (providing they’re not stressed), even if there is no male present, this works out in two ways, either they lay the infertile eggs or in some cases, the eggs get reabsorbed into back into the body.
Fertile Bearded Dragon eggs
Fertile bearded dragon eggs are white in color and will start to swell over a few days, the important things here are heat and moisture. If you notice the egg beginning to sag, don’t worry just add more moisture carefully and the egg should swell up again. If you leave it too long then the egg will die off.
Healthy fertile eggs will positively glow and will double their original size as they swell as the embryo begins to develop.
Incubating the eggs
You can buy custom-made incubators or create your own. Since you’re likely to get many batches of eggs you have the opportunity to test different setups.
- Digital controller with LCD display and LED heat indicator light
- Pulse proportional thermostat for stable temperature regulation
- Temperature control range from 59°F to 104°F
- Humidity Display range from 10%-95% relative humidity
- Rigid 55 watt heating element
First of all the heat source – you can use a light bulb or heat mat or an airing cupboard. Light bulbs are expensive to keep on all day every day for a few months, so I preferred to try heat mats, however, I found that the direct heat from the light bulb above the eggs worked better, but I still had a low success rate using either.
I also tried creating a water bath to retain the heat and this seemed to work marginally better than just heating the incubation tub.
So far I have had a 100% success rate leaving the eggs in the airing cupboard and this is what I would recommend.
Secondly, you need to look at what to keep the eggs in, the small plastic tubs you get the insects in I found are unsuitable, too many small air holes which dried out the eggs too quickly.
Instead, you can get purpose-made plastic hatchling boxes that are of a decent size, cheap, have a lid, and have enough air holes to allow the air to circulate without losing too much moisture.
Thirdly you need a medium to rest the eggs in and to retain heat and moisture, for this I found vermiculite to be the best.
Add it about an inch deep in the tub and add water until it’s all damp and you can leave hollows in it. For each egg create a hollow using your thumb about a centimeter deep and gently move the egg and rest it in this hollow giving at least half an inch in space between the eggs.
It is important to ensure that the egg remains in exactly the same position as it was laid, otherwise turning the eggs could lead to the embryo being malformed or other complications – such as the tail wrapping around and choking the embryo.
But if you want to invest in a purpose-made incubator we recommend Zoo Med ReptiBator Digital Reptile Egg Incubator.
Remember to check on the eggs daily and add more water if it looks dry or eggs begin to shrink.
Incubation times can be as little as 45 days and can be up to 85 days, in my airing cupboard it took about 56 days and the ideal mid-range is about 82 – 86° F if it’s hotter then you risk a higher chance of losing eggs.
Temperature-Dependent Sex Determination (TSD)
Interestingly the temperature at which you incubate the eggs affects the sex of the dragons rather than the chromosomes at the time of fertilization.
Higher temperatures lessen the incubation time but are more likely to create males whereas lower temperatures are more likely to produce females but take longer.
The eggs took between 1 and 3 days to all hatch, the best advice here is to ensure that they are still in a moist environment to prevent the eggshell from drying out or sticking to the newborn bearded dragon.
If there are issues then carefully help the dragon out of the egg, but adequate moisture should prevent the need for this.
When they have hatched transfer them into the vivarium but maintain the temperate the same as the incubator for the first few days. During hatching, if you’re careful you can move them to the vivarium and leave them to hatch there as long as they don’t dry out.

we just found out our beloved beardie is a girl and has layed 10 eggs. they are rather large and off white, almost yellowish and rather oval and football in size. she has not been mated. we have had her for years. i understand you said we can raise them by removing them and keeping them in a warm soil and with moisture. what do i do when they are hatched? do i put them in a new cage all together, do i put them in with their mother? the mothers definitely wont care for the eggs if i keep them together with her? Please write me back. Linda
Hi! Linda. Like many birds and reptiles, female bearded dragons can lay eggs without the presence of a male, but these eggs will be infertile.
Today, my bearded dragon, who I thought was a boy, was apparently a female who laid 6 eggs…turns out all the eggs were yellow on the inside when I shined a flashlight up to it. Was it supposed to be yellow? or only pink? Because I had just thrown out the eggs a few minutes ago.
I’m back, I feel bad because even though the eggs were squishy and yellow inside, I don’t know if maybe at least one of them was actually fertile, I need information on if a non-mated female can have actual babies
If the bearded dragon has never been with a male then you don’t need to worry about it.
My bearded dragon was given to me by a friend and just started laying infertile eggs (about 20) since she hasn’t mated with any male. Will she lay more eggs ? I’ve never had a bearded dragon till now just trying to get some info on it , thanks!
How often a bearded dragon lays infertile eggs is going to vary from one dragon to another. Typically, a dragon can lay several clutches during the “mating season” of infertile eggs, with 20 eggs on average per clutch.
Will they stop eating during the egg laying process?
When close to laying her clutch, your bearded dragon may decrease the amount she is eating or not eat all together.
