Do Chickens Fart? Why and How To Reduce The Smell

If you’re a chicken owner, you may have a lot of questions about your flock. One of the things is farting. We know that humans will fart, and it’s natural to do so. As for chickens, do they fart as well?

So, do chickens fart? Yes, chickens do fart. It’s due to the food that they eat, which will get digested. Some foods will produce gas, will get fermented. The end result will be the chicken releasing the gas through their vent in the form of a fart.

Why Do Chickens Fart?

Farting is something that’s naturally occurring in the digestive system. It is normal for chickens to fart as they need to expel the excessive gas created.

When a chicken farts, there are a number of reasons for it:

  • When the chicken is eating or drinking, they could swallow air. This will result in a fart. If this happens, you may notice air bubbles in the chicken’s poop.
  • Some food could interact with the bacteria in the stomach. Due to the mixture, gas will be produced as a result.
  • Food that is rich in carbohydrates could produce gas. Carbohydrates that are not digested will be broken down into carbon dioxide and hydrogen. When these two are mixed together, a fart will be produced.

Do Chickens Fart Methane Gas?

The fart of chickens is similar to those of humans. It’s made up of the same components for both chickens and humans.

Some foods when it’s digested will produce a lot of bacteria in the guts. This in turn will produce gas in their digestive system. Food that is likely to produce gas is plant-based proteins and dairy products.

As a result of these bacteria in the guts, there will be the fermentation of gas in the gastrointestinal tract. This includes carbon dioxide, hydrogen, and methane.

Do Chickens Fart Smell?

Fart produced by the chickens will smell. This is due to the gas being fermented in the gastrointestinal tract.

Depending on what the chicken eats, the fart can smell really bad or not so bad. Either or, the smell will not be pleasant.

Are Chicken Farts Something To Worry About?

Depending on their fart, it could be a good thing or a bad thing. Chicken that is passing gas on occasion isn’t anything to worry about. It’s normal, and it’s healthy for the chickens, as they need to release the gases from their gastrointestinal tract.

On the other hand, if they are farting too often, it could be a sign of a more serious health issue.

You can’t rely solely on their flatulence to determine the health issue, though. There are other signs that you’ll need to look at too. This can include things like bloating, the smell of their fart is getting worse, and diarrhea.

If you notice anything unusual about your chicken, it’s a good idea to separate them from the rest of the flock. Sometimes, they may be carrying a parasite or disease, and the last thing you want is the pathogens being transmitted to other chickens.

After the chicken is in isolation, determine what’s wrong with them. If you’re unsure, it’s best to take the chicken to the veterinarian for further diagnostic.

Is There Anything That Can Be Done About the Smell?

The mixture that’s produced in the stomach, the odor of the fart, will never smell good.

If the odor is worse than normal, there are a few things you can do to reduce the smell.

One of the things is the food they eat. This is the main cause for a fart that smells worse than usual. Food such as cheese, milk, and other dairy products are known to produce bad-smelling farts.

Another thing is the brand of chicken feed. Poor quality feed tends to use a lot of fillers and additives.

Instead, try using the higher-quality feed. While it’s more expensive, it will use only quality ingredients, which have a good mixture of calcium, protein, vitamins, and minerals.

Besides food, it’s important to keep the coop clean. This means changing their bedding frequently and using high-quality bedding.

Changing their bedding frequently will prevent the smell from accumulating. Chickens are not able to control their waste and will eliminate it everywhere, including the bedding.

As for bedding, use only high-quality bedding. It will help absorb the moisture and odor. This will prevent the smell from getting out of hand.


Chickens do fart, and it’s healthy for them. Farting helps remove excess gas from the digestive tract. You will need to watch them carefully to actually see them fart. Like humans, chickens will fart occasionally, and it will be a couple of times a day.
