Chicken Coop Ventilation: Ideas, Design, Fans, & How To Guide

This article guide explains chicken coop ventilation in detail. It explains how you can ensure ventilation in the chicken coop, it gives you ideas and designs that you can use. Let’s dive into it.

What is Chicken Coop Ventilation?

Chicken coop ventilations are holes in the walls of the chickens’ coops that are either covered in hardware cloth or welded mesh (chicken wire). They let fresh air into the bottom of the coop while the warm stale is let out at the very top of the hen’s house. 

It offers security by keeping snakes and vermin out of the coop. Ventilation in a chicken coop is of two groups: the small vents or pairs of large vents. 

Ventilations are put so that they face away from any prevailing weather to ensure that the air moves freely through the coop, which minimizes drought.

The two types of ventilation for chicken coops:

Passive ventilation: This type allows air to naturally flow through the coop without any outside assistance though the wind can drive roof-mounted units.

Active or forced air ventilation: This involves using artificial means such as electricity to power the fans, allowing air to flow into the coop. It is expensive because of using electricity. However, there are solar-powered fans in the market.

Importance of Ventilation in Chicken Coop

Below are some of the benefits of ventilating your chicken coop:

1. Eliminates Harmful Ammonia Fumes

Chicken dropping contains a great deal of ammonia released into the coop. Ammonia fumes harm your flock because they can lead to irritated eyes, poor overall health, sinuses, respiratory distress, and even death.

High-placed ventilation above the level of the chicken ensures that the ammonia fumes are not trapped inside and they escape. The best way to determine whether your chicken coop eliminates ammonia fumes is to smell for ammonia.

If you detect the smell of ammonia near the coop floor, similar to the chickens’ height, you must increase the airflow.

2. Removes Moisture From the Coop

Chickens generate lots of water vapor through droppings and breathing because they don’t sweat. The water vapor causes the coop to be humid, and high humidity increases the chances of chickens contracting respiratory illness and frostbite

Proper ventilation removes humidity and dampness from the coop. This ensures the chicken will withstand cold temperatures. Frostbite occurs when there are sub-freezing temperatures and moisture. 

It occurs when moisture settles on the wattles, toes, and combs, but keeping the coop ventilated and dry will solve moisture problems.

3. Provides Oxygen-Rich Fresh Air

The high respiratory rate of chickens makes them deplete oxygen and produce large amounts of carbon dioxide. Ventilation in the chicken coop ensures that the chicken gets oxygen, and the carbon dioxide air is replaced by fresh oxygen-rich air.

4. Reduces Airborne Diseases and Microorganisms

High respiratory in chickens makes them susceptible to airborne diseases. Airborne disease organisms build up fast in stagnant air inside the chicken coop, which can infect the entire coop. 

Ventilation in the chicken coop minimizes airborne organisms by allowing fresh air into the coop.

5. Eliminates Respiratory Irritating Dust

Chickens produce lots of dust, and this causes the confined space to be filled with dust particles. 

Chickens have a high respiratory rate and sensitive respiratory systems. For this reason, dust particles need to be removed from the coop to keep the flock healthy.

6. Keeps Your Chicken Coop Cool

Chickens release their heat by breathing which constantly heats the coop. Chickens can handle cold weather, and they do best at low temperatures.

They suffer at high temperatures, which explains why chicken coop ventilation is a must, especially during the warm summer weather.

6. Chicken Coop Ventilation Vs. Drafts

The chicken coop ventilation allows outside air into the space removing stale air. Drafts are defined as currents of air that are drawn into the room. 

The air that flows into the coop using ventilation is required, while drafts don’t enter through windows. They discover even the most minor cracks and enter through them uninvited.

FAQs on Chicken Coop Ventilation

Do you need chicken coop ventilation in winter?

Yes. Chicken coop ventilation in winter is important because it helps to remove odor and moisture build-up. These are hard to rectify, especially during winter. The ridge vents in the chicken coop must remain open all year.

Does your chicken coop need an exhaust fan in summer?

Yes. During the summer, temperatures increase, so your chicken needs to cool off. The heated summer is a recipe for heatstroke, and to ensure it doesn’t happen, you need to ventilate your chicken coop as much as possible. This may include installing an exhaust fan to help your chicken cool off.

Can adding more chicken coop vents be an alternative to a ventilation fan?

Yes. So long as the vents allow unrestricted airflow into the coop, they can be an alternative to ventilation fans that are costly to purchase and maintain.

What are the benefits of cross-ventilation in chicken coop?

Cross ventilation ensures sufficient flow of air because an opening, which can be a door or window, allows stale air to go out through it. 

While fresh air gets into the coop using another opening. Stale air and fresh air don’t have to mix using cross ventilation in a chicken coop.

What is the best direction for chicken coop airflow?

Your chicken coop ventilation air system needs to be put in a position facing the origin of the fresh air. Chickens sleep while facing the direction of the wind and weather. Thus, your ventilation should follow that direction. 

However, remember to build your chicken coop in the east to west direction because it is the best direction of wind flow in most countries. Also, it is the appropriate direction for morning and evening sunlight.


I hope this guide has shed light on everything you need to know about ventilation in the chicken coop. If you use this guide to the latter, you are sure your chicken coop will be adequately ventilated, and your chicken will remain healthy.
