Do Budgies Lay Eggs Without Mating (Find Out!)

Last Updated on January 17, 2024 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? Yes, female budgies can lay eggs without having a mate. It’s a natural thing that can happen even if there isn’t a male budgie around. However, these eggs won’t turn into baby budgies because they haven’t been fertilized by a male.

Budgies can start laying eggs anywhere from 5 months to over 10 years old. It’s essential to know that laying eggs all the time can make a bird lose important nutrients and make her more prone to serious health issues like malnutrition, osteoporosis, and conditions like egg binding and yolk peritonitis.

Due to the stable environment and the constant availability of food, pet budgies can lay eggs all year round. If you see an egg in your budgie’s cage, don’t take it away right then, as she might just lay more to replace it. Instead, wait until she stops sitting on the eggs, and then remove both the eggs and the container.

To prevent excessive egg laying, make sure your budgie has a healthy diet, gets enough sleep, and removes any nesting toys or materials. A balanced diet, regular visits to the vet, and lots of social interaction can also help stop the laying of eggs that won’t hatch.

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?

Determining whether a budgie is gearing up to lay eggs involves paying attention to various signs and behaviors:

  • Bonding and Mating: When a pair of budgies form a close bond and engage in mating, the female typically lays her first egg within an 8 to 9-day window. The male demonstrates courtship by gently tapping his mate’s beak.
  • Nesting Behavior: During the mating season, a hormonal surge in the female may prompt her to seek out nesting spots. This behavior can be accompanied by increased aggression, with the female defending her chosen nest site through fluffing up feathers, loud vocalizations, and even pecking or biting perceived intruders.
  • Physical Changes: Signs such as enlarged droppings, a swollen abdomen, and heightened appetite may indicate that the female budgie is ready to lay eggs. Additionally, the ceres (skin around the beak) of females turn brown during this time.
  • Restlessness and Increased Activity: As the female prepares for egg-laying, restlessness, and heightened activity levels become apparent. Observers may notice her pacing back and forth in her enclosure, struggling to find a comfortable position.
  • Nest Preparation: In anticipation of egg incubation, the female budgie engages in activities to enhance the nest’s comfort. This may involve rearranging nesting materials, including paper strips, soft bedding, or even plucked feathers, to create a snug environment.
  • Changes in Droppings: Budgies exhibit alterations in their bathroom habits, holding their poop longer and producing larger droppings.

While these signs strongly suggest potential egg-laying, they are not definitive proof. If you observe these behaviors and seek confirmation, consulting with a veterinarian or avian specialist is advisable.

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?

Nope, male budgies can’t lay eggs. Only the female budgies have the biological ability to do that.

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

The budgie breeds 4-6 times per year, which enables it to lay eggs 4-6 times per year as well.

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.
