How Long Does It Take for Bird Eggs to Hatch?

Hey there! Have you ever wondered how long it takes for those tiny, adorable bird eggs to hatch? It’s a fascinating process, and the time it takes can vary a lot between different types of birds.

Let’s take a closer look and learn about the hatching of bird eggs!

A Little Birdy Told Me: The Hatching Process

Birds lay eggs, and inside each egg, a little baby bird, or chick, develops. For the chick to grow, the egg needs to be kept warm. This is why you often see parent birds sitting on their eggs in a nest – they are keeping them cozy and warm with their body heat, which is a process called incubation.

Different Birds, Different Times

The time it takes for eggs to hatch depends on the type of bird. Let’s check out a few examples:

  • Small Birds Like Sparrows: Their eggs hatch in about 12-14 days. That’s about as long as it takes for you to get through two weeks of school!
  • Bigger Birds Like Ducks: Duck eggs take a bit longer, usually about 28 days. That’s almost a whole month!
  • Really Big Birds Like Eagles: Eagle eggs can take about 35 days to hatch. That’s over a month of waiting!

Special Cases: The Emperor Penguin

Emperor Penguins are super interesting. The male penguin keeps the egg on his feet under a special flap of skin to keep it warm in the freezing Antarctic. It takes about 65 days for an Emperor Penguin egg to hatch. That’s more than two months!

Why Does Hatching Time Vary from One Bird to Another?

You might be wondering, “Why is there such a big difference in hatching times?” Well, it mostly depends on the bird’s size and where they live. Larger birds generally have longer incubation periods. Also, birds that live in colder places might have longer incubation periods to ensure the chick is fully developed and ready to handle the cold.

Incubation Period of Different Birds

The incubation period of birds, which is the time from when an egg is laid until it hatches, varies widely among different species. This period is crucial because during this time, the parent birds keep the eggs at a constant, warm temperature to ensure the healthy development of the chicks inside. Let’s explore how this period differs across various types of birds:

Type of Bird Incubation Period (Days)
Sparrow 10-14
Robin 12-14
Hummingbird 14-18
Pigeon 18-19
Duck 28
Eagle 34-36
Owl 28-35
Emperor Penguin 64-67
Albatross up to 80

Above table provides a quick overview of how the incubation period can vary greatly among different bird species, from the relatively short time for sparrows and robins to the much longer periods for Emperor Penguins and Albatrosses. ​

Small Birds

  • Songbirds (like sparrows and robins): Generally, smaller birds have shorter incubation periods. For most songbirds, it ranges from 10 to 14 days.
  • Hummingbirds: Known for being tiny, their eggs can hatch in as little as 14 to 18 days.

Medium-Sized Birds

  • Pigeons and Doves: These common city birds usually have an incubation period of about 18 to 19 days.
  • Ducks: For ducks, the period is typically around 28 days, varying slightly among different species.

Larger Birds

  • Eagles: These large raptors have an incubation period that can range from 34 to 36 days, reflecting their larger egg size and the longer development time needed.
  • Owls: Depending on the species, owl eggs can take between 28 to 35 days to hatch.

Special Cases

  • Emperor Penguins: One of the longest incubators, the male Emperor Penguin keeps the egg on his feet for about 64 to 67 days in the harsh Antarctic conditions.
  • Albatross: These large seabirds have an incubation period that can extend up to 80 days, one of the longest among birds.

Factors Influencing Incubation Periods

The incubation period of bird eggs is a critical stage in the reproductive process, where eggs are kept warm and nurtured until they hatch. The duration of this incubation period can vary significantly among different bird species, and several factors play a crucial role in influencing its length. Here are some key factors that impact the incubation periods of bird eggs:

Size of the Bird

One of the primary factors affecting the incubation period is the size of the bird species. Generally, larger birds tend to have longer incubation periods compared to smaller ones. This is because larger birds often have larger eggs, and it takes more time for the embryos inside these larger eggs to develop fully.

Environmental Conditions

Environmental factors play a significant role in determining the length of the incubation period. Birds living in colder climates may experience longer incubation periods. In colder regions, it is essential for the eggs to stay warm and for the embryos to develop adequately before hatching. Longer incubation allows the chicks to be better prepared for the harsh conditions they will face after hatching.

Egg Size

The size of the eggs themselves is another critical factor. Larger eggs typically require a longer incubation period. This is because there is more material to develop within a larger egg, including the embryo, its organs, and the necessary structures for survival. The extra time allows these processes to occur at a pace that ensures the chick is fully developed upon hatching.

The incubation period of bird eggs is not a fixed duration but varies based on several factors. The size of the bird, environmental conditions, and the size of the eggs all influence how long it takes for an egg to hatch.

Nature has finely tuned these variables to ensure that each bird species can adapt and thrive in its specific habitat and conditions, ultimately contributing to the remarkable diversity of bird life on our planet.

Artificial Incubation of Different Birds

Artificial incubation is the process of using man-made methods to hatch eggs instead of relying on the birds to do it naturally. This technique is commonly used in poultry farming, wildlife conservation, and by bird enthusiasts. Let’s explore how artificial incubation is applied to different types of birds.

Here’s a table highlighting the artificial incubation period and conditions for different types of birds:

Type of Bird Incubation Period (Days) Temperature (°F) Humidity (%)
Chicken 21 99.5 40-50, then 65-75
Duck 28-35 99.5-100.0 50-70
Goose 28-35 99.5-100.0 50-70
Parrot (Small) 18-24 Varies Varies
Parrot (Large) 24-28 Varies Varies
Endangered Species Varies Varies Varies

This table provides an overview of the typical requirements for artificial incubation across various bird types. For chickens, ducks, and geese, the conditions are relatively standard, while for parrots and endangered species, the requirements can vary significantly depending on the specific species.

Understanding Artificial Incubation

Artificial incubation involves placing eggs in an incubator, a device that maintains the optimal temperature and humidity levels for hatching. The key is to replicate the natural conditions as closely as possible, including turning the eggs regularly to ensure even warmth, just like a parent bird would do.

Incubation for Domestic Birds

Chicken eggs are commonly incubated artificially, requiring about 21 days at a temperature of around 99.5°F (37.5°C). The humidity is kept at around 40-50% for the first 18 days and then increased to 65-75% for the final days.

These waterfowl have a longer incubation period, typically around 28-35 days. They need slightly higher humidity levels than chickens, often between 50-70%.

Incubation for Exotic and Wild Birds

The incubation periods for exotic birds like parrots vary widely. For instance, small parrots may need about 18-24 days, while larger species like macaws may require up to 28 days. Temperature and humidity requirements can also differ significantly.

In wildlife conservation, artificial incubation is critical for endangered birds. Each species has specific needs, and incubation conditions are meticulously controlled to maximize the chances of successful hatching.

Special Considerations

These are the most critical factors in artificial incubation. Slight deviations can lead to unsuccessful hatching.This mimics the natural behavior of the mother bird and prevents the embryo from sticking to the eggshell.

Regular monitoring is essential to ensure the incubator is functioning correctly and the eggs are developing as expected.

Artificial incubation plays a vital role in bird breeding, conservation, and research. It requires knowledge, precision, and care to successfully hatch eggs, especially when dealing with rare or exotic species. This technology has enabled us to protect endangered birds and enhance our understanding of avian development.

Conclusion: The Miracle of Life

The journey from egg to chick is like a little miracle. Next time you see a bird’s nest with eggs, remember that those eggs are being carefully heated and protected until the little chicks are ready to hatch. It’s a big, wide world of birds out there, with each species following its own special timeline to bring new life into the world.

So, now you know! Whether it’s a tiny sparrow or a majestic eagle, each bird egg has its own schedule for hatching. Isn’t nature amazing?

The incubation period is a fascinating aspect of bird reproduction, showcasing how different species have adapted their breeding strategies to ensure the survival of their chicks. From the tiny, quickly hatching eggs of hummingbirds to the long wait of the albatross, each bird’s incubation strategy is a marvel of nature’s adaptability.


Do birds sit on their eggs all the time?

No, birds do not sit on their eggs all the time. They often take breaks to feed and stretch. However, they ensure the eggs are kept at a consistent temperature, which is crucial for the development of the embryos.

Can bird eggs hatch without a mother?

Yes, bird eggs can hatch without a mother through artificial incubation, where the eggs are kept in an incubator that maintains the necessary temperature and humidity levels.

Do bird eggs need heat to hatch?

Yes, bird eggs need heat to hatch. The warmth, either from a parent bird or an incubator, is essential for the development of the embryo inside the egg.

How can you tell if a bird egg is alive?

To tell if a bird egg is alive, you can perform a process called ‘candling,’ which involves holding the egg up to a light source to see if there are signs of development, such as blood vessels or an embryo.

Can a bird egg survive if cracked?

A cracked bird egg has a lower chance of survival. If the crack is minor, it might be repaired with careful handling and special care, but a severely cracked egg is unlikely to hatch successfully.
