how to tell if a cockatiel egg is fertile

The male cockatiel is always bright blue in the wild, while the female is green. Males and females of cockatiels look different, but both are quite striking. If you own a pet cockatiel and are looking to breed, it is important to know how to tell if a cockatiel egg is fertile. I’ll share reliable tips with you.

A cockatiel egg is not fertile unless it has two eyes and a yolk on its shell. After laying an egg, remove the shell within one minute. During that time period, any presence of eyes and a yolk indicates whether an egg is fertile. Also, you can easily tell if a cockatiel egg is fertile by looking at the color and shape of the egg.

In the world of pet birds, cockatiels are among the most popular and well-known. Before you hatch a cockatiel egg, it is important to find out whether the egg is fertile. Unless you do this, you run the risk of wasting your time and energy on an egg that will not hatch.

Fortunately, in this article, I would like to discuss how can you tell if a cockatiel egg is fertile.

Cockatiel Egg Candling – What Is It?

how to tell if cockatiel egg is fertile

Cockatiel eggs are the perfect size for incubation, but you can’t just put them in an incubator. Make sure the eggs are fertile before incubating. The best way to do this is to candle the eggs.

Cockatiel breeders can determine the fertility of eggs in a new clutch of chicks using a simple technique called egg candling.

You can do this by holding an opaque, bright light about 5-6 cm away from the egg at an angle. When egg candling is performed, light is used to check if an embryo is growing inside the eggshell. After laying the egg, you’ll need to wait 7 days before you can candle it. After sitting on them for 24 hours, you will be able to handle them yourself. 

Usually, cockatiels will wait until they have laid a full batch of eggs before starting to incubate them. On day 7, they will be ready to sit on the nest since they have had plenty of time to warm up.

Your cockatiel has recently started incubating her hatchlings, and you suspect she may be broody. If you are unsure, I suggest watching her behavior before attempting egg candling.

Cockatiels Breeding Period

how do you know if cockatiel eggs are fertile

If you are a cockatiel breeder, you may be wondering how to tell if a cockatiel egg is fertile. There are many ways to tell if an egg is fertile, but the most common way is to see if it is still soft or if it has started to harden.

Cockatiel eggs are typically fertile for about two weeks. The female will lay eggs two to three times a week. These eggs will be a light brown color and the eggs will be slightly smaller than a chicken egg.

Cockatiel eggs are a little more difficult to tell if they are fertile. Females will lay eggs in the nest and then incubate them. 

If the female wants to lay an egg and there is not an egg in the nest, she will pick up a feather and use it to line the nest.

In the wild, cockatiels nest in tree holes, but they use nest boxes in captivity. Cockatiels are seasonal breeders, but some cockatiels will breed year-round.

How To Tell If A Cockatiel Egg Is Fertile?

Cockatiel breeding can be a very rewarding hobby. If you’re wondering how to tell if a cockatiel egg is fertile, the answer is surprisingly simple. Cockatiel owners naturally want to hatch their own cockatiel eggs. The egg must be fertile before investing time and resources into incubating it.

Firstly, you should remove any debris or food that may be present on the egg. Next, shine a bright light on the shell to check for cracks. Finally, touch the egg to check for any bumps or ridges. If you see any of these signs, the egg may be fertile and ready to hatch. In another way, gently press down on the female’s abdomen to check if there are any eggs. They will feel bumpy if there are eggs.

Here, I’ll share a few tips on how do you know if cockatiel eggs are fertile.

Candle An Egg To Look For Growth

You or a cockatiel will be able to see a noticeable change in the appearance of your egg over time if you’ve been incubating it for a few days. 

After just 3 days of incubation, you can candle your egg to see if it is fertile or not. 

Hold your egg up to the light like you would during this process and observe the changes that have occurred over time.

There will be a visible sign of development in a fertile egg, including blood vessel networks, an opaque embryo shape at the egg’s bigger end, and movement within the egg.

Alternatively, an unfertilized egg will appear clear with no blood vessels or rings. There will be rings of blood surrounding an embryo that is no longer viable because it has been deprived of oxygen inside the egg.

Make Sure Your Eggs Float

To hatch your own offspring, you must know that certain eggs sink while others float. However, any egg that sinks is usually not fertile. 

If you are serious about hatching your own bird egg, you should wait until all embryos inside it have developed. 

This is because a newly laid fertile egg may only sink. The egg may also die if it is not incubated correctly.

For best results, take an egg from its container only once a day and preferably earlier on in the process. You can use your cockatiel egg to determine if it’s fertile or not. 

You can observe whether an already laid and incubated chicken egg floats or falls in a bowl of warm water. Then, incubate your fertile eggs immediately.

Examine The Fertile Status Of An Egg

The fertility status of an egg can be assessed easily in this section. If you don’t want to crack open an eggshell to find out if it’s fertile, look for a spot on the egg called a blastodisc.

You can see the blastoderm, the precursor to the chick, in this small area of light color. Watching live eggs is not ideal in many cases unless you are trying to hatch them yourself.

Check your eggs right after they have been laid. Also, put them in a hatcher before they cool off if you want to hatch chicks. 

The first sign that an egg might be infertile would be to see whether any evidence of life is within the shell.

Fertile eggs have a blastoderm, which is a white circle or bullseye. Blastoderm will appear opaque and solid, with pronounced edges. 

Usually, a lighter outer layer, almost transparent, will surround the denser spot.

An infertile egg has a blastodisc that has an irregular shape and a very faint white color.

Note: The blastodisc or white spot is present in all eggs, fertile or infertile.

Don’t Mix Up Your Female And Male Birds

You can create an egg with both male and female genetic material by mating females with males of another species. An unfertilized or female-only created egg is called a blastodisc. 

Blastodiscs are formed by crossing chromosomes, giving them their characteristic banded appearance.

When fertilized eggs or eggs containing both male and female genetic material exists, then the blastodisc has termed a blastoderm.

A blastoderm is an embryonic development stage created by both male and female genetics before the blastodisc.

This depends on how successfully two species interbreed. Blastoderms can be formed either by eggs containing only female genetic material or by eggs that contain both sexes.

Observe The Eggs For 14 To 21 Days

No matter what kind of bird they are. They all take different amounts of time to hatch. After this time, if nothing happens to the egg, it is probably infertile.

If you intend to check hen eggs, you should not use this method. 

The egg will most likely have gone bad after 21 days in an incubator or 7 to 10 days left at room temperature.

Now, I’m going to show you a few signs that a cockatiel egg is fertile and not infertile. You can easily tell the difference.

  • Checking the egg’s air cell is the easiest method. If the air cell is large and round, the egg is not fertile. If the air cell is small and pointed, the egg is fertile.
  • Putting a few drops of hydrogen peroxide on an egg and then watching it bubble up will let you know if the egg is fertile. If it doesn’t bubble up, it is most likely fertile.

Final Thoughts

There are many reasons why someone may want to know how to tell if cockatiel eggs are fertile. You may have a cockatiel as a pet and want to see if she is pregnant. Others may wish to hatch a cockatiel egg for themselves.

Breeders’ Reliable Method is a simple test to determine if the egg is fertile or not. The only thing you need to do is crack the eggshell and examine the insides. 

If it seems complicated and solid, it’s likely that it’s infertile. If it looks soft, with many air bubbles inside you may have a viable egg.

I would like to say that I think the article “how to tell if a cockatiel egg is fertile?”. I found it to be very interesting and valuable. It helped you learn how to care for your cockatiel. 

Additionally, I found out some information about cockatiels that you never knew before. 

Finally, if she doesn’t produce eggs or only gives you a small amount, you should bring her to the vet.

Frequently Asked Questions

How Do You Tell The Difference Between Fertilized And Unfertilized Eggs?

You can tell the difference between fertilized and non-fertilized chicken eggs by candlelight. This is an old farmer trick. Point out blood spots and embryos by holding the egg up to a candle flame. 

Alternatively, you should be able to see differences in the egg’s appearance. A fertilized egg is just like an unfertilized egg on the inside, except that its yolk has a white bullseye.

What Do I Do With Infertile Cockatiel Eggs?

Removing the eggs is the best thing you can do. To ensure your safety, you should wait for the little one to leave the nest before removing any eggs.

However, if she is laying new eggs, replace them with plastic replicas or beads within 48 hours. I believe you’ll agree that removing them safely and gently after this time is better than risking a nasty accident.

In the end, your cockatiel will realize they aren’t going to survive.

How Do You Tell If An Egg Has Died?

If you can hold the large end of the egg up to your ear and you hear tapping noises, it usually means that your chick is about to hatch. You should note any air cells that do not appear fully developed. This could mean the chick has died and will eventually push out from inside. Be aware of an abnormal shadow coming from inside as well.
