At What Age Do Roosters Get Spurs?

At What Age Do Roosters Get Spurs?

Roosters are a fascinating species known for their unique sexual characteristics. One of the most striking features of roosters is the presence of spurs, which are modified hair follicles found on their abdomen. These spurs are typically shed and replaced throughout a roosters life, but the exact age at which they get them is not always clear.

In this article, we will explore the age at which roosters get spurs and provide a comprehensive overview of the process. We will also discuss the factors that influence the timing of spur development, as well as the potential health implications of early or late spur development.

The Age of Spur Development

Roosters are born without spurs, and the development of these structures is a complex and delicate process. The process begins in the embryonic stage, around 30 days after conception. During this period, the embryos sex organs develop, and the testosterone-producing cells, known as Sertoli cells, begin to produce testosterone.

As testosterone levels rise, the Sertoli cells differentiate into the cells responsible for the development of the spurs. These cells migrate to the abdomen and begin to form the spicules, which are the precursors to the spurs. The spicules are initially small and hair-like, but they gradually grow and develop into the mature spurs we see in adult roosters.

The process of spur development is not without its challenges. The developing spurs are highly sensitive to injury, and any disruption can lead to pain and discomfort. Additionally, the process is not fully understood, and there is still no clear consensus on the exact age at which spurs are fully developed.

Factors Influencing Spur Development

Several factors can influence the age at which roosters get spurs, including:

Genetics: Some roosters are more genetically predisposed to develop spurs than others.
Nutrition: A balanced diet that provides the necessary nutrients for proper growth and development can help to promote spur development.
Health: Health conditions such as malnutrition or disease can delay spur development.
Environment: The temperature and humidity of the environment can also affect the rate of spur development.

Potential Health Implications of Early or Late Spur Development

Early or late spur development can have several potential health implications for roosters.

Pain and discomfort: Early spur development can cause pain and discomfort, as the spurs are still developing and not yet fully formed.
Infection: The presence of immature spurs can make roosters more susceptible to infections.
Reproductive problems: Late spur development can lead to reproductive problems, as the rooster may not be able to produce and release sperm.


The age at which roosters get spurs is a complex and multifaceted issue. While the exact age is not fixed, it is generally accepted to be around 12 to 18 months of age. Factors such as genetics, nutrition, health, and environment can influence the timing of spur development.

Understanding the factors that influence spur development is important for ensuring that roosters receive the care they need to develop and maintain healthy spurs. By following the guidelines outlined in this article, you can help to ensure that your roosters reach their full potential and enjoy a long and healthy life.
