Ostriches are famous for laying the largest eggs of any living bird. But how many eggs does an ostrich actually produce?
An adult female ostrich can lay between 40 and 60 eggs per year, although the exact number depends on factors such as age, diet, environment, and breeding conditions.
In the wild, egg production is usually lower because ostriches rely on natural food sources and seasonal conditions. On farms, however, controlled breeding and proper nutrition can increase the number of eggs produced each year.
Understanding ostrich egg production is important for both wildlife enthusiasts and people interested in ostrich farming and egg production.
Quick Answer
A healthy female ostrich typically lays 40 to 60 eggs per year during the breeding season. Under ideal farming conditions, some ostriches may lay even more.
Each egg is enormous compared to chicken eggs and can weigh around 1.2 to 1.8 kilograms (2.6 to 4 pounds).

How Many Eggs Does an Ostrich Lay Per Year?
Ostriches are seasonal layers, which means they do not lay eggs continuously throughout the year. During the breeding season, a female ostrich can lay eggs every two to three days.
Over the course of a full breeding season, this results in a large number of eggs.
| Type of Ostrich | Eggs Per Year |
|---|---|
| Wild ostrich | 10–20 eggs |
| Farmed ostrich | 40–60 eggs |
| High-production farm ostrich | up to 80 eggs |
Farmed ostriches usually produce more eggs because they receive balanced nutrition and live in controlled environments.
How Often Do Ostriches Lay Eggs?
During the breeding season, a female ostrich usually lays an egg every 48 to 72 hours.
The laying cycle continues for several months. This means a single ostrich can produce dozens of eggs within one season. Egg laying often slows down or stops completely once the breeding season ends.
Ostrich Breeding Season
The breeding season for ostriches depends on climate and geographic location. In most regions, it begins in spring and continues through late summer.
During this time, males establish territories and attract females. Several females may lay eggs in the same nest, which is known as a communal nest.
A dominant female usually lays her eggs first, and these eggs often receive the best position in the nest.
How Many Eggs Are in an Ostrich Nest?
Ostrich nests can contain a surprisingly large number of eggs. Because several females may use the same nest, a single nest may contain 20 to 60 eggs However, only a portion of these eggs usually hatch successfully.
The dominant female and the male share incubation duties. The female usually incubates the eggs during the day, while the male takes over at night.
What Affects Ostrich Egg Production?
Several factors influence how many eggs an ostrich can lay each year.
1. Age of the Female
Young ostriches may produce fewer eggs. Egg production often improves once the bird reaches full maturity, usually around two to three years of age.
2. Nutrition
Diet plays a major role in egg production. Ostriches that receive balanced feed with sufficient protein, vitamins, and minerals tend to lay more eggs.
A poor diet can reduce egg production or lead to weaker eggs.
3. Environmental Conditions
Temperature, daylight hours, and stress levels can affect laying cycles. Stable conditions usually support better egg production.
4. Breeding Management
On farms, breeders carefully manage mating groups and nesting conditions. Proper management often results in higher egg yields.
Why Ostrich Eggs Are So Large
Ostrich eggs are the largest eggs produced by any living bird. A single egg can weigh as much as two dozen chicken eggs combined.
The large size provides enough nutrients to support the development of a chick that is already quite large when it hatches.

Incredible Strength: Despite being an egg, the shell is surprisingly thick and strong (about 2 mm). It is so durable that an adult human can often stand on an ostrich egg without it breaking! This strength is necessary to protect the developing chick from the weight of the parent during incubation.
Ostrich Eggs in Farming
Egg production is one of the main reasons people raise ostriches.
Ostrich eggs have several uses:
- breeding new chicks
- food production
- decorative carving
- crafts and art
Some farms sell fertilized eggs for breeding, while others sell unfertilized eggs as food products. Because each egg is so large, a single egg can feed several people.
Artificial Incubation: On many commercial farms, eggs are removed from the nest and placed in industrial incubators. This trick often encourages the female to lay more eggs than she would in the wild, as she tries to “refill” her nest.
Natural Incubation: Preferred for organic or small-scale farming, allowing the parents to raise the chicks, which often results in hardier birds.
How Long Does It Take for an Ostrich Egg to Hatch?
Once an egg is laid and fertilized, the incubation period is relatively long compared to most birds. Ostrich eggs typically take about 42 days to hatch.
During incubation, the eggs must remain at stable temperatures. Both the male and female play an important role in protecting and warming the nest.
Nature’s Camouflage: The female ostrich, with her grayish-brown feathers, sits on the eggs during the day to blend in with the earth. The male, with his black feathers, takes over at night to remain invisible to predators in the dark. This tag-team approach significantly increases the survival rate of the eggs.
FAQ
How many eggs does an ostrich lay at once?
A female ostrich usually lays one egg at a time, typically every two to three days during the breeding season.
How many eggs does an ostrich lay per year?
Most female ostriches lay 40 to 60 eggs per year, although production may be lower in the wild.
How big is an ostrich egg compared to a chicken egg?
An ostrich egg is about 20 to 24 times larger than a typical chicken egg and can weigh up to 1.8 kilograms.
Do male ostriches lay eggs?
No. Only female ostriches lay eggs. However, male ostriches help incubate and protect the eggs.
Do ostriches lay eggs all year?
No. Ostriches are seasonal layers. Egg production usually happens during the breeding season, which often lasts several months.
