Do Budgies Lay Eggs Without Mating (Find Out!)

Last Updated on July 21, 2022 by Ali Shahid

It is common for some budgie owners to let their flock increase and let their birds lay eggs. But you must have heard about a single budgie laying an egg. However, how can one budgie lay an egg? Do budgies lay eggs without mating?

Budgies indeed lay eggs even when they are not mated. It is believed that hormones play a major role in the stimulation of the female reproductive cycle in budgies. When the external signs of a suitable environment are present, then those hormones are released at the same time.

Female budgies will still lay unfertilized eggs even without the presence of a male budgie. In both wild budgies as well as pet breeding pairs of budgies, egg-laying is expected behavior.

Wild budgies are most likely to reproduce in springtime when food is abundant and temperatures are mild, resulting in breeding behavior and the development of young birds.

Due to the stable environment and the constant availability of food, pet budgies can lay eggs all year round. Despite most people believing budgies can only lay eggs when they are paired up, this is not true.

A female budgie can also lay eggs without a male. Keep reading to know why budgies lay eggs without mating.

Can Female Budgies Lay Eggs Without A Male?

A female budgie can lay eggs even if she lives alone or if she shares a cage with other female budgies. As soon as external factors signal to their bodies that the time is right to reproduce, budgies begin to form eggs in their nests.

Light factors and other bird calls can affect egg production, not just a male’s presence. A budgie, for instance, knows that spring has arrived when it is exposed to more sunlight.

The weather will be conducive to raising chicks during this time of year, and food and water will be abundant. Upon reaching this point, the female’s body releases hormones that prepare her for reproduction.

After that, she will begin to search for a male to mate with. The fact that a male isn’t present does not matter since her body is already preparing eggs for conception even if he isn’t there.

Some egg-laying animals can retain sperm for a long period, but budgies can’t. So it follows that copulation must take place while the female is developing the egg within her body. It is still necessary to lay the eggs if the eggs are not fertilized.

Unfertilized eggs may confuse the female, and she may sit on them as if they were viable and incubate them. A young budgie that is new to both mating and parenting is likely to exhibit this behavior.

The female or you will have to throw them away after some time when they begin to rot.

 How to Know If a Budgie Is Going to Lay Eggs?

Budgies usually tell you when eggs are coming by their behavior more so than their appearance. When a budgie is expecting an egg, it may appear heavier or rounder, but it isn’t always because of the egg.

The more nest-building behavior your budgie engages in, the more likely it is that you will notice it. In the case of a nest box in her cage, for example, you may notice that she spends more time in it when you have one.

The chances of a budgie laying an egg very shortly are very good if there is a nest being built somewhere in their cage.

Can Budgies Lay Unfertilized Eggs?

It is important to keep in mind that a female will only lay unfertilized eggs unless she is maintained with a male. A budgie cannot reproduce asexually, and a female is not capable of storing sperm from a male to fertilize her eggs in the future.

There is a possibility that your budgie’s breeding session will fail even if it is kept with a male. There is a possibility that young budgies do not have the level of experience and that the sperm may not reach or fertilize the egg at all.

The method of laying unfertilized eggs is the same as that of laying fertilized eggs. It will be impossible to tell the two apart at first glance, and most budgies will also experience this issue.

It is going to take the budgie a few days before he realizes that the egg is not developing the way it should. It is at this point that a more experienced mother will push the egg out of the nest.

Fertilized Vs Unfertilized Eggs

I would like to mention that you may have a female budgie that is laying eggs, and you have no idea if the eggs are fertilized or not.

Your female budgie may not have spent much time with a mating partner, or maybe you have been trying to get fertilized eggs from a breeding pair. Males and females can unintentionally mate in pet shops and breeders where cages aren’t separated.

If you’ve waited for a mated pair to produce fertilized eggs, they usually appear about 10 days after the mating. It is very simple to determine if a female budgie’s eggs have been fertilized by using a flashlight. All you have to do is look for such a light source.

It is called egg candling. Using a flashlight, turn it on and point it directly upwards, then move the egg closer to the light so that you can get a clearer idea of what is happening inside the egg.

A fertilized egg will exhibit veins running through its interior, which indicates that it has been fertilized. On the other hand, if you look at an unfertilized egg, you will only see a yolk.

Handling Unfertilized Eggs

The smell of rotten eggs is one of the most recognizable smells there is. Taking good care of your budgie’s cage means removing any eggs that have not yet been fertilized as soon as possible.

There is, however, a limit to how fast you’ll be able to get rid of the eggs, which is determined by the behavior of the budgie. Birds that become attached to their eggs will experience great stress from removing them quickly, making the situation worse.

Consider taking a few minutes to observe the behavior of your budgie around the eggs before deciding to remove them. You will have little trouble removing the eggs if your budgie isn’t interested in nesting or sitting on them.

In case the bird is incubating fertile eggs, it may take a few days for it to realize that they are not worth caring for.

Frequently Asked Questions

Can a male budgie lay eggs?

The male of a bird species rarely lays eggs, which is the case for most bird species. Males and females have clearly defined roles in raising a chick due to a uniquely tuned reproductive evolution.

How many times does a budgie lay eggs in a year?

As a rule of thumb, budgies, starting from the age of around five months old, can lay as many as 24 eggs per year, depending on the circumstances.

As far as number is concerned, there are several eggs spread out in groups called “clutches.” The number of clutches can vary from two to three each year.

When do budgies lay eggs after mating?

Following mating, an egg develops a shell and must be paid by the female a few days later, so it is not an immediate process. They will continue to mate whether she lays an egg or not, and she will lay six eggs every clutch.


All in all, we can conclude based on all these discussions that budgies can lay eggs without mating. However, these eggs won’t be fertilized. Fertilization of an egg requires the presence of sperm.

In the case of budgies laying eggs without mating, it is impossible to achieve this. As a result, the eggs laid will not be fertilized, and they will need to be disposed of after laying to prevent contamination of the cage.
