So today, we are going to talk about everything you need to know about chicken coop ventilation. And we will give you our 11 best types of chicken coop ventilation for every climate and coop style.
So you are designing your own chicken coop and keep coming across adding ventilation. But, what does that even mean?
Ventilation is probably one of the most crucial elements of your coop. Without proper ventilation, your chicken’s health could be at stake.

Chicken Coop Ventilation vs Draft
Before we go much further, defining what we mean by ventilation is crucial. Chicken coop ventilation is intentional points where air can enter the coop and circulate back.
A draft is unprotected holes in the floors or walls of your coop. Vents serve a purpose and can be adjusted for different seasons. Drafts can not be controlled and will let too much cold air in.
Drafts could also let pests into your coop. A coop should be well-ventilated but have no drafts.
Why Do I Need Ventilation?
The 11 best types of chicken coop ventilation serve a variety of purposes. For instance, aeration is a must if you live in cold weathered climates.
Well-placed ventilation reduces the amount of moisture in the air during the winter. Chickens fare well during winter, but the humidity could cause painful frostbite.
Without ventilation, moisture will quickly build up and cause respiratory illnesses.
In hot summer months, ventilation provides a cool breeze inside the coop. A coop without ventilation might as well be an oven.
Strategically placed vents will keep your coop at a tolerable level. And finally, vents also allow harmful ammonia to escape.
Ammonia is a natural by-product of feces decomposing, and we all know chickens poop a lot. Vents will help with the smell and keep the air clean.
How Much Ventilation Is Needed?
The amount of ventilation needed depends on how large of a coop you have. A general rule is that for every 10 sqft of floor space, you need 1 sqft of ventilation.
But if you live in hotter-than-average areas, more ventilation is always welcome. Some people even make one side of the coop a screen for ventilation in the South.
Where Should Ventilation Be Placed?
Chicken coop ventilation can be placed in several areas depending on your climate. Chicken coop ventilation in winter months should be up high.
Ideally, you want the vents above the head so you don’t let in a direct stream of cold air. And for hot weather, you want ventilation lower to the floor and even at roosting and nesting height.
But most of us don’t live in climates where it’s only hot or cold. So what should we do? The most straightforward answer is closing lower vents.
Add enough ventilation high up for winter and lower for summer. A few windows can also work great for the summer because they can be closed off.
Installing as much ventilation as you can in various places allows you to control your coop’s temperature better.
11 Best Types Of Chicken Coop Ventilation
Now that you know everything about vents, you can see our recommendations. These vents are fantastic for any chicken coop design.
You can customize a pre-fabricated coop with these vents to fit your needs.
Holes With Hardware Cloth
One of the cheapest types of ventilation is holes drilled into the side of the coop. These holes are usually placed along the top of the coop and covered from the inside with hardware cloth.
These vents are significant for people who live in mild climates and can be installed in any coop. The only downside is that they can’t be closed, so drilling them too low is not an option.
Windows
Every chicken coop should have a few windows with a hardware cloth screen. Windows are fantastic for letting in light, allowing you to see in, and as ventilation.
You could add windows on opposite walls to create a cross-ventilation chicken coop. Cross-ventilation is excellent for hot and humid summers.
It lets a breeze through your coop and wicks away moisture. It also can cool your chickens and get rid of smells.
You can get small windows at any hardware store in various sizes. And if you are looking for recycled materials, you can often find them for free.
Screen Doors
Screen doors can give your chickens many of the same benefits as a window. They allow lots of sunlight and air to get into your coop and are inexpensive.
Screens doors are available at any home improvement warehouse, and you can also salvage them for free. If you use a screen door, don’t forget to add another solid door for protection.
Some people even decide to replace the flimsy screen with hardware cloth to ensure their chickens are kept safe.
Screen Sides
Another option for a cross-ventilation chicken coop is to have removable siding. These coops can be a little more challenging to build, but they are beneficial for hot weather.
If you make two sides of the coop removable, then your coop can have hardware cloth sides. This method allows for the maximum amount of ventilation.
But when you put the sides back on for winter, ensure no drafts are coming in.
Many people like the clean look of this Rocky Mountain Goods Air Return Grille. They are perfect for ceiling ventilation or lower to the floor.
And since these vents close, you can adjust ventilation according to the season. When installing these, you want to make sure they are screwed into place well from the outside.
If not screwed in tight, raccoons could quickly get into your coop at night.
Magnetic Vent Cover
And if you are worried about your metal vents letting in a draft, these magnetic vent covers are perfect.
These covers go right over any metal vent to keep as much air from getting through as possible. That makes them great for winter-proof any vents lower to the ground.
