Do Chickens Fart? A Fun Fact!

Do chickens fart - funny picture of wondering chicken

You may have heard some speculation about whether or not chickens fart, and we’re here to get to the bottom of this great feathered mystery.

It’s a topic that has been debated for years with no clear answer.

Some chicken keepers claim they’ve heard a “toot” here and there, while others are adamant that this is simply not possible.

So, do chickens really fart?

In this blog post, we will delve deep into the world of chicken farting and provide you with all the facts you need to finally put this age-old debate to rest.

Do Chickens Fart?

As it turns out, yes, chickens can indeed fart.

Just like any other animal with intestines, air pockets can become trapped in their digestive tract, and they have to come out one way or another.

However, it’s not as easy to detect a chicken fart as it is with some other animals.

Chickens are constantly producing gas, so it’s unlikely that you’ll hear a loud fart from a chicken.

Instead, the gas is released gradually, making it hard to detect.

One thing that may surprise you is that chickens can also burp.

Yes, you read that right!

Chickens actually have a digestive system that is similar to that of a human, which means that they can burp up excess air just like we do.

So, the next time you hear one of your feathered friends burping, you’ll know that it’s perfectly normal.

But why do chickens produce gas in the first place? Well, it all comes down to their diet.

Chickens are notorious for having a ravenous appetite and will eat just about anything they can find.

This includes foods that are rich in fiber and can be more difficult to digest, such as vegetables and fruits. 

As a result, they produce more gas than other animals with a simpler digestive system.

Now, you may be wondering if chicken farts are harmful to their health.

The good news is that, in most cases, they are not. It’s a natural bodily function that helps to release excess gas, and as long as their digestive system is healthy, there should be nothing to worry about.

Still have questions about your chickens’ flatulence? We’ll continue to break things down in this post.

A chicken's digestive system

How Does a Chicken’s Digestive System Work?

To understand chicken farts a bit better, we need to take a closer look at how a chicken’s digestive system works.

A chicken’s digestive system begins in its beak, where it uses its tongue to move food around and break it down into smaller pieces.

Chickens don’t have teeth, so they rely on the gizzard to grind up their food.

The gizzard is a muscular organ that sits just after the crop and before the small intestine.

It’s filled with small stones, which the chicken ingests to help break down the food it eats.

When the gizzard muscles contract, the stones grind up the food into smaller pieces, which can then be digested more easily.

Once the food has been broken down in the gizzard, it passes through the small intestine, where most of the nutrients are absorbed.

The small intestine is lined with finger-like projections called villi, which increase the surface area available for absorption.

This allows the chicken to extract as many nutrients as possible from its food before it is excreted.

Next, the food passes through the ceca.

These are blind pouches at the beginning of the large intestine, which are filled with friendly bacteria and enzymes that help break down any remaining food matter.

The bacteria in the ceca produce vitamins and other nutrients that are essential for the chicken’s health, such as vitamin K.

The ceca also helps to reabsorb some of the water that has been lost during digestion.

Finally, the waste material passes through the colon and out of the bird’s vent.

Chickens excrete both solid and liquid waste, which is why their droppings are made up of both feces and urine.

They are remarkably efficient at producing droppings, and can produce up to one pound of waste per day.

What Causes Chickens to Fart?

You might find it funny to think about a fluffy bird breaking wind, but it’s actually a natural process.

Here are some reasons why your chickens might be a bit gassier than normal:

Certain Foods

Just like humans, chickens can also get gassy if they consume certain types of food.

Sulfur-rich foods like onions and garlic, spicy food, soybean and canola, leafy greens, and dairy are some of the main culprits.

Feeding your chicken a balanced diet without too much of these types of food will help minimize gas production.

Poultry Disease

Marek’s disease is a virus that affects the nervous system of chickens, and one of its symptoms is an enlarged abdomen.

This can lead to more gas being trapped in the chicken’s digestive system, causing excessive farting.

If you suspect your chicken is suffering from Marek’s disease, it’s best to bring them to a veterinarian as soon as possible.


Just like any other animal, a chicken can also experience allergies.

If you’ve noticed that your chicken farts more frequently after coming into contact with a particular substance like pollen or dust, then it’s possible that they’re experiencing allergic reactions that lead to gas build-up.

Obesity (Fatty Liver Syndrome)

As surprising as it may sound, chickens can also get fat.

Overfeeding your chicken with high-fat foods such as seeds and grains can lead to a condition known as Fatty Liver Syndrome.

This condition causes fat to accumulate in the liver, leading to more gas production and consequently more farting.

Non-Digestion of Carbohydrates

Chickens are unable to digest high fiber and complex carbohydrates efficiently, leading to an accumulation of gas within their digestive systems.

If you’ve noticed that your chicken has been eating lots of grass or other fibrous plants, then be prepared for more frequent bouts of farting.

Just Regular Passing of Air

It’s important to note that chickens, like all living beings, need to release gas every once in a while.

Just like how humans pass gas, chickens do it too.

So, if you’ve been noticing occasional farts from your chickens, then there’s no need to worry—this is normal.

What Do Chicken Farts Smell Like?

It’s no secret—chickens are not picky eaters.

They will devour just about anything, including insects, worms, small rodents, seeds, vegetables, and even their own poop.

This diet makes them efficient at converting food into energy and laying eggs, but it also means their farts can be noxious.

Chickens are known to emit a wide range of gasses from their digestive system, including nitrogen, carbon dioxide, methane, and various sulfides.

Studies have found that canola-and-soy-fed chickens produced farts with significantly more sulfur compounds and a stronger odor than the control group.

So, what does this mean for your chicken coop?

If you want to minimize the odor of chicken farts, you might want to avoid feeding your birds a diet high in sulfur-containing foods.

This includes many types of beans, legumes, and cruciferous vegetables, such as broccoli, cauliflower, and brussel sprouts.

However, keep in mind that chickens need a balanced diet that includes protein, fat, and carbohydrates, so you shouldn’t cut these foods out completely.

Of course, not everyone is bothered by the smell of chicken farts. In fact, some people find it amusing or nostalgic.

If you’re one of those people, then you can take heart in knowing that chickens are natural gas producers, and their farts are a sign of a healthy gut microbiome.

The microbes in their digestive system break down food into nutrients and glasses, and the gasses have to go somewhere.

What Does a Chicken Fart Sound Like?

Now that we know that chickens fart and why, the next question is whether these farts can be heard.

The truth is that chicken farts are not audible in most cases.

This is because the gas that they produce is usually released slowly over time, which makes it difficult to hear.

The sound of a chicken fart is very soft, so it can be easily overpowered by other sounds.

However, there are some instances where chicken farts can be heard.

For example, if a chicken is trying to force out gas quickly, it can create a sound.

This is usually a soft “puff” or “pop” sound.

It is not very loud, but it can be heard if you are very close to the chicken.

Additionally, if the chicken has gas build-up in their crop (the first part of their digestive system), it can produce a more audible sound.

It is also important to note that the size and breed of the chicken can affect the sound of their farts.

For example, a larger breed of chicken may produce a slightly louder sound than a smaller breed.

Some chickens may also have digestive issues that can cause louder farts.

One thing to keep in mind is that just because you don’t hear your chickens farting, it doesn’t mean that they aren’t doing it.

In fact, most chickens fart up to 30 times a day!

Therefore, it is safe to assume that your chickens are producing gas, even if you can’t hear it.

Chicken Manure

Do Chicken Farts Release Methane?

So do chicken farts produce methane, a potent greenhouse gas linked to climate change?

It may seem like a silly question, but it is actually a serious concern for the environment, as poultry farming is a large contributor to greenhouse gas emissions.

Chicken manure does release methane.

In fact, it’s considered to be the third largest source of methane from livestock manure management.

While this may not seem like a lot on a per bird basis, consider that there are billions of poultry birds in the world.

The poultry industry is a large contributor to greenhouse gas emissions.

In fact, according to a report from Mississippi State University, the poultry industry in the United States alone produces approximately 9% of greenhouse gas emissions from animal agriculture.

This is primarily due to the production of waste, including manure and the associated methane emissions.

Nevertheless, it’s an important issue to address as greenhouse gas emissions are linked to climate change.

The good news is that you probably don’t have to worry too much about your chickens’ farts contributing to global warming.

On a small scale, breaking a bit of wind here or there isn’t anything to be concerned about.

If you’re worried about your environmental impact as a chicken keeper, take the time to compost your chicken manure—that won’t stop the farts, but it will make the best possible use of the manure as it relates to the environment.

Do I Need to Worry About My Chickens Farting?

An occasional fart isn’t something to worry about.

However, if you start to notice that your chickens are farting a lot and that the smell is worse than usual, you might want to pay closer attention.

Excessive gas and a bad odor could be a sign of other digestive problems that could impact your chicken’s overall health.

Flatulence in chickens is often associated with bloating, which is when their bodies are unable to expel gas efficiently.

This can cause stomach discomfort, which can lead to decreased appetite and diarrhea.

If you notice your chickens frequently bloating and farting, you should consult with a veterinarian to check for any underlying issues.

Another possible cause of excessive farting in chickens is from a sudden change in their diet.

Chickens’ digestive systems are sensitive to different types of food, and if you introduce something new too quickly, they might struggle to digest it, leading to gas and bloating.

Therefore, if you want to change their diet, it’s important to do so gradually so that their digestive system can adjust properly.

In addition to dietary changes, stress can also cause chickens to pass gas.

Chickens who are experiencing stress, such as through overcrowding, environmental changes, or because of predator exposure, may develop digestive problems that could lead to flatulence.

To prevent this, it’s important to ensure your chickens are housed in a comfortable environment with enough space that meets their needs.

Finally, it’s worth mentioning that not every gas a chicken releases is from their behind.

Hens can often make a similar noise as a fart when they lay their eggs.

So, if you notice your chicken producing a sound that you think is flatulence, it could just be a sign that she’s about to lay an egg.

How to Reduce Smelliness in Your Chicken Coop From Chicken Farts

Have you ever visited a chicken coop and been hit by the pungent smell of chicken farts?

Here are some common reasons why your chickens’ farts (or even their manure) might be stinkier than normal.

Feed Brand or Ingredients

The food your chickens eat can play a significant role in the smell emanating from their farts.

Certain brands of feed can cause your chickens to produce more gas, which leads to a bad odor in your coop.

Look for brands that are specifically formulated to be low in gas-producing ingredients.

Another way to reduce smelliness is by feeding your chickens high-quality food, which contains fewer fillers and more healthy ingredients.

Quality feed can also improve the digestion process, resulting in fewer farts.

Keep the Coop Clean

One of the most important steps in reducing odor inside the coop is by keeping it clean.

This includes changing litter frequently, removing wet droppings, and cleaning water and food dishes regularly.

Improve Ventilation

Proper ventilation is crucial for a healthy environment inside the coop.

Adequate airflow will help to reduce moisture levels, odor, and ammonia gasses.

A simple way to increase ventilation is by installing windows, vents or fans.

Move the Feeder

Chickens that eat at ground-level swallow more air, leading to more farting.

By putting the feeder up higher, it will keep them from swallowing air bubbles, hence reducing flatulence.

Try Probiotics

Providing your chickens with probiotics can help to balance the digestive system by promoting good bacteria and reducing bad bacteria.

Activated charcoal is also known to absorb gas-producing substances in the digestive tract, reducing smells and boosting their immune system.

Yes, Chickens Do Fart!

Chickens may not be the first animal that comes to mind when you think of farting, but the truth is that they can and do produce gas.

It’s all a part of their normal digestive process, and as long as they are eating a healthy diet and their digestive system is functioning normally, there should be no cause for concern.

So the next time someone asks you the question, “Do chickens fart?” You can confidently say, “Yes, they sure do!”
