Can Cockatiel Eggs Hatch Without A Male?

A female cockatiel will develop eggs once her hormones are activated, not due to mating with a male. Instead, social and environmental signals, such as light cycles and vocalizations, trigger these chemicals. But, can cockatiel eggs hatch without a male?

Can Cockatiel Eggs Hatch Without A Male?

Can Cockatiel Eggs Hatch Without A Male? If a female cockatiel has had no contact with a male before laying eggs, the eggs will not hatch. As a result, the eggs will be unfertilized, and you will need to dispose of them. Also, if your female cockatiel regularly lays eggs without hatching, this can be damaging to her body.

However, if the eggs aren’t fertilized, they will still need to be laid. The female may become confused after laying the unfertilized eggs and sit on them, incubating them as if they were viable.

This behavior is expected in younger cockatiels new to mating and motherhood. They will eventually rot and need to be thrown out by the female cockatiel or yourself.

A female cockatiel lays on average 4-6 eggs per clutch, which she lays one at a time over the coming days. However, since no breeding occurred, the eggs are unfertilized and will never hatch.

But, a female cockatiel may still brood over her eggs, believing they are fertilized. However, as they won’t hatch, remove them once the female ceases to show interest in them.

Furthermore, you can control this behavior by adjusting to her living environment and daily routine.

Can Female Cockatiels Lay Eggs Without A Male?

Just like in humans, reproduction in female cockatiels is instigated by hormones.

However, unlike humans, who have a natural internal cycle, the reproductive cycle of cockatiels is based more on what is happening around them.

The season, temperatureOpens in a new tab., and other external factors can cause a female cockatiel to begin forming an egg.

It definitely isn’t necessary for a male to be part of that process. Female cockatiels can lay eggs regardless of whether or not they have mated.

What mating will change whether or not the egg is fertilized? A fertilized egg has a small cockatiel growing inside it, while an unfertilized egg does not.

Can Cockatiels Lay Unfertilized Eggs?

If a female cockatiel is not kept with a male, the eggs will not hatch. This is because cockatiels are incapable of asexual reproduction, and a female can’t store a male’s sperm to fertilize her eggs.

Even if your cockatiel is kept with a male, their breeding session may be a failure. This is because younger cockatiels may lack experience, and sometimes the sperm doesn’t reach or fertilize the egg.

The same process applies to the laying of fertile and infertile eggs. You cannot tell the difference at a glance, and most cockatiels will face the same problem.

It will take a few days for the cockatiel to realize that the egg isn’t developing properly. More experienced mothers will now force the egg out of the nest.

Fertilized Vs. Unfertilized Eggs

Fertilized Vs. Unfertilized Eggs

Let’s say you have a female cockatiel laying eggs, and you aren’t sure if they are fertilized.

Maybe you have been trying to get fertilized eggs from a breeding pair or just aren’t sure whether your female cockatiel has spent time with a mating partner.

Unintentional mating can occur because some pet stores or breeders don’t keep males and females in separate cages.

If you have been waiting for a mated pair to produce fertilized eggs, it might help to know that fertilized eggs can take about 10 days to show up after a successful mating.

However, a helpful way to determine if an egg is fertilized is to “candle” it. This involves holding a light source, such as a phone’s light, up to the egg until it is illuminated. Then, if there is a developing embryo, it will be visible.

In addition to the embryo, check for a network of blood vessels. This can be hard to see if your light source isn’t powerful enough. If needed, use a bright flashlight.

The viability of an egg cannot be determined until it has been incubated for 7 days, making freshly laid eggs difficult to analyze.

What Should You Do With Unfertilized Eggs?

Unfertilized eggs will spoil and go rancid, so you will need to remove them from the cage and dispose of them as you see fit.

There are two courses of action you can take, depending on how the cockatiel reacts to the eggs:

  • Immediately – this works if your cockatiel ignores the eggs and doesn’t become distressed.
  • Over a few days – exercise patience if your cockatiel nests and broods over the unfertilized eggs.

It can be distressing to take her eggs away, so she may become aggressive when you react to them or frantic after they are gone. So, keep an eye out for when she stops trying to nest or realizes the eggs are infertile.

At this point, you can remove the eggs without upsetting or disturbing her.

How Often Do Cockatiels Lay Unfertilized Eggs?

Wild cockatiels have 1 to 3 clutches per year, with 4-6 eggs in each clutch. The Evolution of BeggingOpens in a new tab. predicts that each egg will be laid two days apart.

According to Experimental Gerontology, cockatiels show no signs of reproductive aging. However, discrepancies between wild and captive cockatiels’ reproductive cycles.

Domesticated cockatiels are rarely exposed to the natural cycles of nature because they are usually kept indoors and are exposed to artificial light, which may confuse their hormones.

Link-dark cycles play an important role in determining when cockatiels mateOpens in a new tab.. In addition, these cycles, which are called the photoperiod, indicate the changing seasons.

As winter becomes spring, the day grows longer and the nights shorter. Instinctively, cockatiels know that this means food will be in abundance.

Other breeding cycle inducers include caressing on the back, reflectionsOpens in a new tab., and other birds’ vocalizations.

Is It Dangerous For Cockatiels To Lay Unfertilized Eggs?

Is It Dangerous For Cockatiels To Lay Unfertilized Eggs?

Many complications may occur if you leave your cockatiel to lay unfertilized eggs. Here are some of them:

1. Calcium deficiency

Eggs are made of calcium. So when a cockatiel forms an egg, it takes the calcium from its body to make it.

Egg forming and laying is a laborious process. When a cockatiel’s calcium levels are low, it can cause health issues, such as bone fractures.

2. Stress

Cockatiels become hostile after egg-laying because they don’t want anything to happen to their clutch.

The stress of caring for eggs may cause behavioral issues aside from hostility. Lethargy, unwillingness to eat, and feather plucking are all things that result from a cockatiel getting stressed.

3. Egg-binding

Egg binding occurs when a cockatiel cannot lay an egg that has already been formed internally.

However, if the egg remains inside for long periods, it can lead to infection and organ damage.

The egg can also break while inside the cockatiel. The oviduct tube may become infected from scratches caused by the shell fragments.

4. Hostility

Cockatiels that lay can become hostile and protective. But, on the other hand, the caring, lovable cockatiel that would never hurt you won’t hesitate to lunge for your fingers if you dare get close to its eggs.

5. Strokes

Excessive egg laying may lead to stroke. Blood can become thicker because of nutrients that are transported through the bloodstream to help with egg formation. Eventually, circulation issues can arise.

How To Stop Cockatiels From Laying Infertile Eggs

It is advisable to put preventative measures in place to deter cockatiel breeding behavior. Risks associated with egg production and laying include stressOpens in a new tab..

Here are some proven methods you can use:

  1. Don’t provide a nesting box.
  2. Control the photoperiod, so the female doesn’t think it’s spring year-round.
  3. Keep males and females cockatiel separate.
  4. Don’t pet a cockatiel below the neck.
  5. Move items around the cage as we approach spring.

Of course, if your cockatiel still lays several clutches of eggs or constantly struggles with egg-laying, hormone injections and salpingectomies are an option.


In conclusion, female cockatiels may still lay eggs without a mate. After all, their hormones, not their mating season, determine how many eggs they produce.

Your cockatiels might lay eggs as a result of different social and environmental causes.

Still, this will only result in a clutch of unfertilized eggs, so it is wise to discourage them from doing this if you want to keep them healthy.
