Chicken Coop Ventilation – Is It Really Important?

The weather is getting warmer, and if you don’t want your chickens to overheat in the coop during the day, it’s important to make sure they have enough ventilation. This blog post will give you some tips on how much ventilation a chicken coop needs and what other factors can affect how much ventilation your chickens need.

Is It Important To Add Ventilation To Your Chicken Coop?

Adding ventilation to your chicken coop is important for the health of your flock. A lack of air flow in a confined space will cause humidity, which can lead to respiratory problems like pneumonia or even death.

Ventilation in the coop will provide fresh air that’s not polluted by bacteria from their droppings and other gases produced inside the coop.

Chicken also cause lots of ammonia fumes to be released from their droppings, and in a closed up chicken coop this will cause respiratory problems.

Providing a good chicken coop ventilation also helps to control the temperature inside your chicken coop by regulating how much fresh air gets in order to maintain an even climate.  

What is the Best Time to Ventilate the Chicken Coop?

Many chicken owners believe that the best time to ventilate their coop is during summer when it’s warm and dry outside.

However, this is not true. It’s important to have ventilation in the chicken coop all the time (winter and summer, day and night) because it helps prevent disease and allows chickens to breathe easier.

How Much Ventilation Does a Chicken Coop Need?

To ensure that your chickens are healthy, remember to give them enough ventilation.

A good rule of thumb is for every ten square feet of chicken coop, you should have one square foot of vent opening.

How to Add Ventilation To Your Chicken Coop?

There are a few ways to add ventilation to your chicken coop, including adding fens, holes, windows or a cupola. Ventilation holes should be strategically placed in the roof and wall of your chicken house so that cold air can circulate freely without getting trapped inside with the chickens.

Chicken Coop Cupola

A chicken coop cupola offers a better way to give your chickens the fresh air they need. A cupola is an open-air structure that sits on top of the roof, allowing light and air into the building below it.

It provides ventilation in a different way than windows or vents do by providing a direct flow of air from outside.

Cupolas provide relief during hot summer months when chicks are at their most vulnerable stage, as well as protection during extreme weather conditions like storms.

As you can see there are many benefits to having a chicken coop with an attached cupola!

Ventilation Holes

This is probably one of the easiest way to add ventilation to your chicken coop. Ventilation holes are a simple and inexpensive way to provide your chickens with the fresh air they need.

They work by allowing hot inside air to escape so that cooler outside air can enter, all while keeping rain (or snow) out of the coop.

You can drill ventilation holes on your own, but don’t forget to cover the holes with wire mesh to keep predators out.


A fen is a vertical ventilated wall that works in the same way as ventilation holes by providing fresh air to your chickens and keeping rain (or snow) out of the coop.

They are made from vinyl or aluminum, which makes installation easy for any DIY-er!

Final Thoughts

Remember, a chicken coop with too much or not enough ventilation can lead to your chickens overheating in the summer or freezing during winter months.

But if you have a coop with good ventilation, your chickens will be able to enjoy and be comfortable year-round.

I hope that this blog post has given you some helpful tips on how much ventilation a chicken coop needs and what other factors can affect the amount of ventilation needed.
