Unraveling the Mystery: Why Do Chickens Eat Their Own Feathers?

why do chickens eat their own feathers

Have you ever noticed your chickens eating their own feathers and been left wondering why? Feather eating behavior in chickens can be concerning to poultry farmers, as it can lead to various consequences, including cannibalism and nutritional deficiencies. In this article, we will explore the reasons why chickens eat their own feathers, including possible causes, natural instincts, and behavioral factors. By understanding feather consumption in chickens, you can take steps to prevent it and maintain a healthy flock.

Understanding Feather Eating in Chickens

Feather consumption is a common behavior observed in chickens, but it can be concerning for poultry farmers and owners. Understanding the causes of feather eating and plucking can help prevent these behaviors and promote healthy flock dynamics.

Causes of Feather Eating in Chickens

A number of factors can contribute to feather eating in chickens. One common reason is a nutritional deficiency. Chickens require a balanced diet that includes adequate protein and other essential nutrients to maintain healthy feathers. If their diet is lacking in these nutrients, they may turn to eating feathers as a source of protein. Other potential causes of feather eating include boredom, stress, and overcrowding.

Feather Plucking in Poultry

Feather plucking can also be a cause of feather eating in poultry. This behavior can be triggered by a number of factors, including stress, disease, and overcrowding. Chickens may pluck each other’s feathers as a way to establish dominance or to gain access to resources like food and water.

In addition to causing feather eating, feather plucking can also lead to injuries and infection, as the exposed skin is more vulnerable to damage and disease.

Preventing Feather Eating in Chickens

To prevent feather eating in chickens, it is important to address the underlying causes of the behavior. This may include providing a balanced diet, reducing stressors like overcrowding or noise, and offering enrichment activities like perches and pecking blocks. If feather plucking is observed, it is important to isolate any birds that are being targeted and to treat any injuries or infections as necessary.

By understanding the causes of feather eating and plucking, poultry farmers and owners can take proactive steps to promote healthy flock dynamics and prevent potentially harmful behaviors.

Cannibalism in Chickens: The Dark Side of Feather Eating

Feather eating behavior in fowl can have more serious consequences than just a lack of feathers on their bodies. Chickens that consume feathers may develop cannibalistic tendencies, attacking and even killing other birds in their flock. Cannibalism is a serious issue that can lead to injury and death among chickens, as well as a breakdown in social dynamics within the flock.

It’s important to note that not all instances of feather eating will lead to cannibalism, but it is a potential risk. Chickens that are bored, stressed, or have inadequate nutrition may be more likely to engage in cannibalism, as they search for alternative sources of stimulation or sustenance.

If cannibalism becomes an issue in your flock, it’s important to take swift action to prevent further harm. This can include separating birds that are engaged in aggressive behavior, providing more space and enrichment to reduce boredom and stress, and ensuring that all birds are receiving proper nutrition.

Feather eating behavior can be a warning sign of deeper issues within the flock, and should not be ignored or dismissed. By addressing the root causes of this behavior, you can help ensure a safe and healthy environment for your chickens to thrive in.

Natural Instincts: Instigating Feather Consumption

Chickens, like many other birds, have natural instincts that drive their behavior. These instincts have evolved over thousands of years and are deeply ingrained in their DNA. One of these instincts is the drive to preen and groom themselves, which includes the removal of loose feathers.

In the wild, chickens and other birds will often eat their own feathers as a way to recycle nutrients back into their bodies. Feathers are rich in protein and other essential nutrients, and by eating them, birds are able to replenish their stores of these nutrients.

Domestic chickens still retain this instinct, and will often eat their own feathers even when they are well-fed and have access to plenty of other food sources. This behavior is particularly common in birds that are kept in confinement and have limited access to space or environmental stimulation.

Research has also suggested that certain breeds of chickens may be more prone to feather eating behavior than others. For instance, some breeds that have been selectively bred for high egg production may be more likely to exhibit this behavior, potentially due to the increased nutritional demands placed on their bodies.

Nutritional Deficiencies: Feather Eating as a Sign

If your chickens are exhibiting feather-eating behavior, it’s possible that they may have a nutritional deficiency. Feathers are made up of a protein called keratin, which is essential for healthy feather growth. If your birds are not getting enough protein in their diet, they may resort to eating their own feathers to get the nutrients they need.

To prevent feather-eating behavior caused by nutritional deficiencies, it’s important to ensure that your birds are getting a balanced diet with sufficient protein. This can be achieved through feeding them a high-quality commercial feed or supplementing their diet with sources of protein such as mealworms or crickets.

Additionally, offering your chickens access to grit can also help with nutrient absorption and digestion, which can reduce the likelihood of feather eating.

Finally, keep in mind that feather eating behavior can also be caused by boredom or stress, so it’s important to assess all potential factors before determining the root cause.

  • Ensure your chickens have plenty of space and access to natural light and fresh air.
  • Provide them with a variety of toys and items for enrichment, such as mirrors, perches, and hanging treats.
  • Minimize stress factors such as overcrowding or sudden changes to their environment.

By addressing nutritional deficiencies and providing a stimulating environment for your birds, you can help prevent feather eating behavior in your poultry flock.

Environmental Factors and Feather Eating

Feather plucking in poultry is often a response to environmental factors that can induce stress in chickens. Overcrowding in coops, for example, can cause chickens to become agitated and begin to peck at each other and themselves. This behavior can lead to feather plucking, which can then lead to cannibalism if not addressed.

Other environmental factors that can trigger feather plucking include insufficient food and water, inadequate lighting, and poor ventilation. It is important to maintain a clean and healthy coop environment, with enough space for each chicken and plenty of nesting boxes, to mitigate these issues.

One way to reduce boredom and eliminate stress in chickens is by providing them with enriching activities, such as perches, dust baths, and toys. This can help to reduce feather plucking behaviors and improve overall flock health. Additionally, trimming the sharp edges of chicken beaks can reduce the damage done during feather plucking.

Overall, it is important to closely monitor the behavior of your chickens and address any issues immediately. By addressing environmental factors and providing enriching activities, you can help prevent feather plucking in your flock and maintain a healthy, happy group of chickens.

Behavioral Causes: Boredom and Feather Consumption

Feather eating behavior in fowl can also be attributed to boredom and other behavioral factors. Chickens that do not have enough space to roam, access to objects to peck at, or opportunities to engage in natural behaviors may turn to feather plucking and consumption as a way to occupy themselves.

In addition, chickens that have experienced trauma, such as an attack by a predator or a change in flock dynamics, may also develop feather eating behavior as a coping mechanism. This can lead to a vicious cycle, as feather eating can cause further stress and health problems.

To prevent feather eating behavior due to boredom or trauma, it is important to provide chickens with an enriched environment that allows for natural behaviors. This can include access to perches, dust baths, and objects to peck at, as well as providing a secure and spacious living area.

Chickens that have developed feather eating behavior may also benefit from behavioral modification techniques, such as positive reinforcement training or introducing new sources of stimulation. It is important to address feather eating behavior as soon as possible to prevent it from becoming a habit.

  • Provide chickens with a spacious living area and access to objects to peck at.
  • Address trauma and stress factors that may contribute to feather eating behavior.
  • Consider behavioral modification techniques to prevent feather eating habits from forming.


In conclusion, chickens may eat their own feathers for a variety of reasons, including natural instincts, nutritional deficiencies, environmental factors, and behavioral causes. Feather eating behavior can have negative consequences, such as cannibalism and flock dynamics, but can also signal underlying health issues in poultry. To prevent feather consumption, it’s important to ensure that chickens have a balanced diet, adequate space, and appropriate enrichment activities. By understanding the causes of feather eating in chickens, farmers and backyard poultry keepers can take steps to promote the health and well-being of their flocks. So, the next time you wonder why do chickens eat their own feathers, remember these potential factors and strategies for prevention.
