Do Budgies Lay Eggs without Mating?

A female budgie will start to develop eggs inside her once hormones are activated, not because a male was involved.

Environmental and social signals trigger these chemicals, including light cycles, vocalizations, and petting the bird below the neck.

The eggs can’t be reabsorbed. Since no breeding occurred, the eggs will be unfertilized and never hatch.

Female budgies can lay eggs, even if they haven’t bred with a male. That’s because egg production occurs regardless of mating.

Unlike mammals, a female budgie doesn’t form her eggs once they’ve been fertilized. If her hormones trigger egg production, that process will be carried out with or without a mate.

A budgie can lay 4-6 eggs in a single clutch, and these eggs will be laid one at a time over several days.

Female budgies may still brood over their eggs as if they were fertilized, and they should be removed once she shows no further interest in nesting them.

Can Female Budgies Lay Eggs Without A Male?

Even if a female budgie lives alone or shares a cage with other females, she may lay eggs. Budgies start to form eggs when external factors tell their bodies that it’s the right time to reproduce.

This can be due to the presence of a male, but it’s usually connected to light factors and other bird calls. For example, exposure to more sunlight tells a budgie that spring has arrived. Food and water will be abundant, and the weather will be favorable for raising chicks.

At this point, the female’s body will release hormones ready for reproduction. Then, she’ll start looking for a male. It doesn’t matter if one isn’t present because her body is already forming eggs in readiness.

Unlike some egg-laying animals, budgies can’t retain sperm from a previous breeding season. So, copulation must happen while the egg is developing within the female.

If the eggs aren’t fertilized, they won’t be reabsorbed into the budgie, so she’ll need to lay them. Once she has laid the duds, she may grow confused and sit on the eggs, incubating them as if they were viable. This is common in younger budgies that are new to mating and motherhood.

They’ll eventually rot and need to be thrown out, either by the female or yourself.

Can Female Parrots Lay Eggs Without A Male?

All parrots can lay eggs without a male.

It’s less common than with chickens, but it happens. Chickens only lay daily due to selective breeding to promote this trait. Since parrots or other members of the psittacines family haven’t been exposed to this genetic modification, they don’t lay eggs as regularly.

Nonetheless, parrots have a natural desire to further the species in the most effective way they can. Parrots don’t know in advance if all their eggs will be fertilized or when. To achieve a higher success rate, their bodies produce eggs in advance and do their utmost to get them fertilized.

If your budgie isn’t exposed to any mating signals, such as light and vocalizations, its body will have no reason to prepare the eggs.

As far as it’s concerned, breeding isn’t an option. For this reason, you may own a budgie or another breed of parrot for years without finding a single egg.

All it takes is something to trigger the budgie’s hormones and this changes. Egg-laying without a male occurs across the entire family of true parrots.

However, the smaller breeds, like budgies and cockatiels, do so more frequently. They’re more vulnerable as prey animals, after all, and need to maximize their reproduction rate to maintain the species.

Can Budgies Lay Unfertilized Eggs?

It’s not harmful to a budgie to lay unfertilized eggs.

Unless a female is kept with a male, that’s all she’ll produce. Budgies are incapable of asexual reproduction, and a female cannot provide sperm to make her own eggs viable.

Even if your budgie is kept with a male, their breeding session may be a failure. Younger budgies may lack experience, and there are times when the sperm doesn’t reach or fertilize the egg.

Unfertilized eggs are laid in the same way as fertile eggs. You’ll be unable to tell the difference at a glance, and most budgies will also struggle.

It’ll take a few days for the budgie to realize that the egg isn’t developing correctly. At this point, more experienced mothers will push the egg out of the nest

What To Do With Unfertilized Eggs

Unfertilized eggs will spoil and go rancid. At some point, you’ll 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 budgie reacts to the eggs:

  • Immediately: This works if your budgie ignores the eggs and doesn’t become distressed.
  • Over a few days: If your budgie nests and broods over the unfertilized eggs, exercise patience.

It can be distressing for the budgie if you take her eggs away. She may become aggressive when you reach for them or frantic after they’re gone. Wait for her to lose interest in nesting or realize the eggs are infertile. At that point, you can take the eggs without unsettling her.

Unfertilized eggs can be disposed of with your everyday food scraps.

How To Tell If An Egg Is Fertilized

A useful way to determine if an egg is fertilized is to candle it.

This method involves holding a light source, such as your phone’s light, up to the egg until it is illuminated. If there’s a developing embryo, it’ll be visible.

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

Newly laid eggs are hard to parse. It’s near impossible to tell if an egg is viable until it is 7 days old.

How Often Do Budgies Lay Unfertilized Eggs?

Budgies have 2-3 clutches per year in the wild, with 4-8 eggs in each clutch. According to the Evolution of Begging, each egg will be laid 2 days apart.

This will continue throughout the budgie’s life since Experimental Gerontology notes that budgies show no reproductive aging in nature. However, there are some discrepancies between the cycles of wild budgies and captive budgies.

Domestic budgies are rarely exposed to the natural cycles of nature. They’re often kept indoors and are exposed to artificial light, which may confuse their hormones.

Light-dark cycles play an important role in determining when budgies mate. These cycles, which are called the photoperiod, indicate the changing season.

As winter becomes spring, the days grow longer and the nights shorter. Instinctively, budgies know that this means food will be in abundance.

Pet budgies can have more laying periods than wild budgies. Their bodies think it’s summer and spring, thus the best time to raise chicks. Other signals that trigger a breeding cycle include vocalizations from other birds, mirrors, and petting on the back.

How To Stop Budgies From Laying Infertile Eggs

It’s sensible to implement preventative measures to discourage breeding behavior in budgies. Egg production and laying pose several risks, including stress.

Here are some methods you can use:

  • Control the photoperiod budgies experience, so she doesn’t think it’s spring year-round
  • Don’t provide nesting boxes
  • Keep males and females separate
  • Don’t pet a budgie below the neck
  • Move items around the cage in the lead up to spring

Of course, if your budgie still lays an abnormal number of eggs or always seems to struggle with egg-laying, hormone injections and salpingectomies should be considered.  

Dangers Of Egg Laying

If your budgie routinely lays eggs, the main danger is egg-binding.

This condition is where the budgie cannot pass or lay the egg due to it becoming lodged or breaking internally. This leads to numerous health conditions, which can be fatal if left untreated.

Budgies have a singular vent through which they lay eggs and poop. A vent blocked by an egg means she’s unable to pass waste.

According to Seminars in Avian and Exotic Pet Medicine, when eggs break internally, egg yolk peritonitis can occur. This is when the egg yolk leaks into the abdominal cavity and not the oviduct, where the egg is formed. That will cause inflammation and other health complications.

Female budgies can lay eggs without coming into contact with a male budgie. These eggs are unfertilized, so it’s wise to discourage egg-laying. Unfortunately, egg-laying can’t be avoided entirely.
