What is diatomaceous earth?
Diatomaceous earth is famous for most chicken owners. It is a white poriferous powder composed of the fossilized remnants of the tiny aquatic organisms, known as diatoms. Silica is the term called for the skeletons of diatomaceous earth made up of a natural substance. It is the significant component of DE that makes each variety different from the other.
The Organic Minerals Research Institute has included diatomaceous earth in their list of organic products. It is a non-profit organization that thoroughly reviews all products according to their organic standards.
Diatomaceous earth is a multipurpose product primarily used for our everyday lives, such as a pesticide, skin products, and a lot more.
There are various types of diatomaceous earth, but food-grade DE and pool-grade DE are commonly used. You should provide to your chickens should be the Food Grade diatomaceous earth because it is absolutely safe for your poultry.
It comprises practically pure amorphous silicon that makes it safe for humans and animals. On the other hand, pool-grade DE is composed chiefly of crystalline silica that can lead to silicosis.

Food grade vs. Non-food grade diatomaceous earth?
There are various varieties of diatomaceous earth, but if we talk about its safety and benefits for chickens, we will tackle the food grade and the non-food-grade DE or what is known to be the pool grade DE.
Diatomaceous earth is being graded whether it can be allowed for humans and animals or known as the food-grade DE, or only used for filtering called the pool grade.
Most Food Chemical Codex Grade diatomaceous earth products comprise below 1% of crystalline silica. A food-grade DE is considered to be healthy and safe to use for both animals and humans. A Food grade DE is composed of amorphous silica, which does not really have significant health concerns once inhaled and is considered non-toxic.
On the other hand, a non-food-grade DE is mainly used for filtration and is not meant to be used for all living things as it may cause harm.
When DE is superheated, it then forms crystalline silica, making up a pool-grade DE—making it not safe for anyone, whether animals or humans, to inhale it. Regular inhalation of pool-grade DE might cause you to be at a higher risk for lung cancer. Regardless if it is food-grade or pool-grade, it is still recommended that you take precautions.

What are the disadvantages of Diatomaceous Earth to chickens?

- Unlike chemical pesticides that react promptly once applied, diatomaceous earth needs a little time to work effectively. It usually takes hours and days to work entirely.
