Why Do Chickens Eat Their Own Poop


Chickens, known for their quirky behaviors, sometimes engage in a rather puzzling activity: eating their own feces. While this behavior might seem repulsive to us, it’s actually quite common among chickens and many other animals. This post delves into the intriguing phenomenon of chickens eating their own poop, exploring the reasons behind this behavior, its potential benefits, and the risks associated with it.

Reasons Why Chickens Eat Poop

Natural Instincts and Evolutionary Factors

Chickens are not engaging in this behavior arbitrarily; it’s rooted in their genetic makeup. In the wild, chickens’ ancestors had to make the most of available resources to survive. Pecking at droppings enabled them to find undigested grains, seeds, and nutrients, providing an evolutionary advantage. This behavior stems from their natural instinct to conserve energy and make the most of available food sources.

Competition for Resources in the Wild

In the wild, food can be scarce, and competition among animals for nourishment is fierce. By consuming their own droppings, chickens could obtain additional nutrition that might have been missed during their initial digestion. This strategy allowed them to gain an upper hand in the competition for limited food resources.

Potential Dangers and Risks

Health Hazards of Consuming Feces

While this behavior might have conferred advantages to chickens in the wild, it poses significant risks in a modern context. Eating their own droppings or those of other animals exposes chickens to harmful bacteria and parasites. Pathogens like salmonella, Campylobacter, E. coli, and avian viruses can be present in feces, leading to various health issues in chickens and potentially even transmitting diseases to humans who consume undercooked chicken.

Significance of Regular Examination

To ensure the health of your flock, it’s crucial to periodically examine their droppings. Runny and discolored feces can be indicative of illness, warranting immediate attention. By staying vigilant and attentive to these signs, you can take proactive measures to address any potential health problems within your flock.

Taste Perception and Processed Chicken

Taste Perception Differences

One intriguing aspect of this behavior is the difference in taste perception between humans and chickens. Chickens lack the elaborate taste buds that humans possess and might not be able to distinguish between their feed and their own droppings. This factor could play a role in their inclination to consume poop.

Fecal Matter in Processed Chicken

The matter becomes more complex when we consider the presence of fecal matter in processed chicken. Regulations and standards regarding fecal matter content vary across different countries. In the United States, for example, there are regulations and inspections in place to address visible signs of fecal matter on processed chicken. Despite these efforts, studies have found traces of fecal matter in a percentage of tested chicken products, raising concerns about food safety.

Other Animals Consuming Poop

Wide-Ranging Phenomenon

Interestingly, the behavior of consuming feces isn’t unique to chickens; many other animals, both herbivores and omnivores, engage in this practice. Dogs, despite being carnivores, are known to exhibit poop-eating behavior as well. Some speculate that this behavior might be linked to malnutrition.

List of Animals Engaging in Coprophagy

The list of animals participating in coprophagy is extensive and includes species such as orangutans, gorillas, rhesus monkeys, hippopotamus calves, baby elephants, and more. This behavior underscores the broader nature of this phenomenon across the animal kingdom.

Benefits of Chickens Eating Poop

Enhancing the Digestive System

Chickens possess a specialized organ called the crop, which contains microorganisms aiding in digestion. Young chicks, introduced to these microorganisms by pecking at older chickens’ droppings, benefit from this microbial boost to their digestive systems.

Harvesting Extra Nutrition

Chickens also capitalize on the potential for extra nutrition in droppings. Insects are attracted to feces, and chickens seize the opportunity to consume insect eggs, larvae, and worms present in the poop. This behavior supplements their diet with additional protein-rich food sources.

Eliminating Harmful Parasites

Surprisingly, chickens can act as their own pest control agents. By consuming droppings that contain harmful nematodes and parasitic worms, chickens help keep their populations in check. This serves as a natural defense mechanism against these potentially detrimental parasites.

Managing Harmless Waste

It’s important to note that the majority of the microorganisms present in healthy animals’ droppings are harmless. The feces mainly consist of waste from digestion and undigested particles. While the thought of this might be unsettling to us, for chickens, it’s a way to manage their waste while also reaping potential benefits.

Cons of Chickens Eating Poop

Spreading Diseases

One of the most significant concerns associated with chickens eating poop is the potential spread of diseases. Chicken diseases can be transmitted through fecal matter, and sick chickens can infect healthy ones. To mitigate this risk, isolating sick chickens is imperative to prevent the spread of pathogens within the flock.

Learning and Imitation

Chickens are social creatures that learn from one another. If one chicken engages in poop-eating behavior, others might imitate it, leading to a potential chain reaction. Isolating chickens exhibiting this behavior can prevent its spread throughout the flock.

Preventive Measures

To discourage chickens from eating poop, implementing preventive measures is essential. Regularly removing droppings from the coop and providing alternative treats can divert their attention away from this behavior. In some cases, isolating chickens in specific situations might also be necessary.

Chickens’ Eating Habits

Varied Palate

Chickens are notorious for their adventurous eating habits. Their diet extends beyond feed to include a diverse array of items, such as bugs, grass, small mammals, and even dirt. This broad spectrum of consumption aligns with their natural behaviors and survival instincts.

The Truth About Chickens Eating Poop

The notion that chickens eat their own poop is indeed true. This practice, known as coprophagy, is a natural behavior deeply ingrained in their evolutionary history. Chickens have evolved to engage in this behavior for various reasons that are connected to their survival and nutritional needs.

Universality of Coprophagy

Chickens aren’t the only animals that indulge in coprophagy. This behavior is witnessed in a range of creatures, including rabbits, guinea pigs, lemurs, chimpanzees, dogs, and cats. While the reasons might vary, the prevalence of this behavior across species underscores its significance in the animal kingdom.

Reasons for Eating Poop

Nutrient Retrieval

Chickens eat their own poop for specific reasons. First, it’s a way to retrieve nutrients that might have been missed during the initial digestion process. By consuming their feces, chickens have a chance to absorb these overlooked nutrients.

Immunity Boosting

Second, eating poop might play a role in enhancing chickens’ immunity. Probiotics and beneficial microorganisms present in the feces can contribute to the development of a healthier gut environment, supporting the overall well-being of the chickens.

Sense of Smell and Taste

Lastly, it’s possible that the sense of smell and taste of chickens makes their own poop appealing to them. While it might seem puzzling to us, chickens might be attracted to certain scents and flavors that we don’t fully understand.

Risks Associated with Eating Poop

Bacterial and Parasitic Content

Chicken poop isn’t just a benign waste product; it can harbor a range of harmful bacteria and parasites. Diseases such as coccidiosis, Salmonella, avian influenza, Campylobacter, and fowl cholera can be transmitted through chicken poop. These diseases can lead to serious health issues and even death, both in chickens and in humans who come into contact with contaminated surfaces or consume undercooked chicken.

Chicks and Coprophagy

Even young chicks exhibit coprophagy, but there’s an ongoing debate about whether this behavior should be encouraged or discouraged. Chicks are more susceptible to diseases due to their developing immune systems, making them more vulnerable to pathogens present in feces. Some poultry keepers advocate for maintaining clean living conditions to discourage this behavior until chicks mature and develop stronger immunity.
