DE is Old School Practice, Today We Know Better
Using diatomaceous earth (DE) in your coop or in dust baths poses a threat to both you and your chickens, as it results in the continuous presence of dangerous irritant particles in the air. Diatomaceous earth (DE) serves no essential purpose, raises safety concerns, and proves ineffective for its claimed applications.
The primary concern with using DE is the fine dust that it creates when handled. When under a microscope, you can see that Diatomaceous Earth is fine and very sharp. Inhaling this dust is a lung and respiratory irritant, potentially leading to respiratory issues. I’m not just talking about this being a danger to your chickens, but to you as well. As you well know, there are always particles in the air when you are cleaning the coop, maybe from a windy day, or just from your birds scratching around looking for bugs. Once you lay down DE you are putting yourself and your birds at risk, even if you put shavings on top. If you’re wondering if food grade DE is safe, the answer is NO.
If you’re not concerned about lung and respiratory problems, the other issue with using DE is irritation to the skin and eyes, especially in the dry powder form.
So, if you’re going to use DE, I hope you don’t mind wearing a mask, gloves, and protective eyewear. And, if you don’t mind putting your chickens’ health at risk or wearing hazmat apparel when caring for your chickens, then go ahead and use DE… but you have been warned of the consequences.
