What is diatomaceous earth? And what’s the benefits to chickens?

 

 

No worries. I had no clue either.

 

We started using DE on our farm a while ago, and haven’t looked back since. We had a number of Cornish Cross chickens which had gotten so large they couldn’t clean themselves very well any more. 

 

 

But they liked to roll!

To help them keep bug free, we started offering boxes of diatomaceous earth with regular sand dirt for them to use. And it was a hit!

 

 

The other chickens LOVED it, and the amount of mites and lice on them began to reduce. So we were sold.

 

 

You can find diatomaceous earth in any feed store. If you want to purchase it over Amazon, here’s a great option:

 

 

But what is this stuff anyway?

 

Diatomaceous earth is the crushed shells of diatoms (aquatic alge) that have fossilized into substrate in aquatic sites.

 

 

Those sites are mined, and boom! Powdered diatomaceous earth is born (okay, that’s a very quick boom, but I’m not going to bore you with details.)

 

The upshot is that diatomaceous earth is mostly silica, clay minerals, and iron oxide – all good, natural stuff.

It’s also great to use in your soil since it kills soft-body insects by eliminating necessary oils from their body, causing the bugs to dry out.

 

Yup, kind of gross, but good for your chickens.

 

Food grade vs. non-food grade diatomaceous earth

 

First things first. If you want to offer diatomaceous earth to your chickens, you need to make sure it’s FOOD GRADE diatomaceous earth.

Here’s the deal:

 

That little food grade label means it’s safe for anyone, even people, to eat. Without that stamp, you’re taking a chance.

 

Chickens that bathe in diatomaceous earth will likely try tasting it too. As long as you offer food grade diatomaceous earth to your chickens, it’s okay if they eat it.

 

It’s unclear whether chickens derive any health benefits from eating it, but at the worst, it’ll do nothing.

 

Ok, so what good is diatomaceous earth?

Great question. There’s a couple answers.   Diatomaceous earth is proven to be effective in controlling external parasites on your chickens, such as mites, fleas, lice and other external parasites that might infest near feather follicles or your hen’s vent.

A good place to look for mites is around your chicken’s vent.

In a study performed by the University of California Riverside, chickens that rolled in a dust bath of sand and diatomaceous earth showed a huge reduction in the amount of external parasites after just a week – pretty powerful stuff.           If you have chickens that aren’t laying as well, it might possibly be caused by mites. If your chickens have to fight of an infestation, they have less energy for egg production.

So what’s the bad news?

 

As great as it is for external parasites like mites, diatomaceous earth has spotty results when it comes to internal parasites.

 

One study performed in Vancouver showed that diatomaceous earth is effective in controlling internal parasites, and the chickens were heavier and laid more eggs when fed diatomaceous earth.

 

However, studies in the US have been largely unsuccessful.

 

That doesn’t mean it doesn’t work, just that some studies show it works while other studies show diatomaceous earth does nothing to reduce internal parasites (like worms) in chickens.

 

It’s inconclusive.

 

The bottom line?

 

I would venture to say we really don’t know how effective diatomaceous earth is when it comes to internal parasites.

 

But here’s the thing:

 

We know it isn’t likely to do anything bad, and the bottom line is that if your chickens are bathing it it, chances are they’ll sample it too. They’re curious creatures like that.

 

So, whether it’s effective or not, they’re likely getting it anyway.

 

How to use diatomaceous earth

 

Making a diatomaceous earth box

 

The easiest way to incorporate DE into your coop is by offering a dust box loaded with a diatomaceous earth/sand or dirt mix. There’s really no formula for how much of either to offer, so I go with a 1:1 ratio. 

 

I found when I offered a box with diatomaceous earth alone, the chickens looked at me like I’d grown a second head, and they didn’t use it. So, I recommend mixing it with dirt so your chickens get the idea.

 

I first line the box with dirt, then add the diatomaceous earth and mix slightly so the chickens get the idea that it’s not just this weird grey stuff.

 

If you plan to offer your DE box in a run, you will need to remove it when it rains, otherwise you’ll be left with a gloppy mess. If you offer it in the coop, then you’re golden. 

 

 

Sprinkling it in dirt

 

Another option, if you don’t want to make a DE box is to simply sprinkle the diatomaceous earth in an area where your chickens already habitually roll. 

 

 

This is a good option for chickens who aren’t quite getting the idea of using a DE box or who just prefer a good roll in the dirt.

 

 

Simply sprinkle DE in their favorite roll area and let them use it at will. The diatomaceous earth will still be effective.

 

Offering diatomaceous earth in food

 

While the effects of diatomaceous earth in controlling internal parasites is inconclusive, you can still offer it to your chickens in their feed. 

 

 

An added benefit is that DE is proven to control insects in livestock feed since it dries the little buggers out, and there are chicken farmers out there who mix DE with their chicken feed, especially if they buy a lot of it and store it. 

 

 

Nothing is worse than feed that’s gotten infested (ask me how I know.)

 

 

There’s no proven formula for mixing DE in their food. One good option is to simply sprinkle a dusting on their dinner and mixing before offering it to your chickens. 

 

 

The advantage to mixing the DE into the feed is the diatomaceous earth will cling to the feed (whether you feed a grain, scraps, corn, etc.) and your chickens are more likely to get it into their system than if you simply sprinkle it on top.

 

 

You can also offer it separately. Remember, also, your chickens will likely sample it as they roll in it, but if you want more control over the amount of diatomaceous earth they consume, mixing it into their feed is a great option.

 

 

If you use my homemade organic chicken feed recipe, another option is to sprinkle it on the fodder. It will stick to the wheat (or barley) sprouts and your chickens can eat it that way. 

 

The effects of diatomaceous earth are still being studied, but with the mounting evidence that it’s effective in controlling mites, lice, and other external bugs, it’s something you should try in your own coop!

 

I’d love to hear from you!

  1. very good article! I agree with your stance on using DE powder. It won’t hurt and it usually helps. Also, the photos in this post are pretty amazing!

  2. We are building our coop this year and getting our chickens next. I just wanted to thank you for all the wonderful information you share. 🙂

  3. I am going out and adding DE to the chickens’ favorite roll spot right now. I feed DE to our Bison/Buffalo all year long. Really gets rid of flies, and I believe gets rid of the worry of internal parasites. The studies may be inconclusive, but I have taken critter shit from our pasture in to have it tested multiple times over multiple years and it always comes back negative. Really don’t know why I hadn’t thought of giving it to the hens, but your story makes perfect sense and am starting today. All I have to do is walk to the feed barn and get a can and they are up and running! Thanks!

  4. Good morning, how often do you add diatomaceous earth to the ground ? I have a 10 x 20 area.

  5. I have DE for my pets and their flea issues. I will definitely be using it for my chicken farm. I’m glad I found your blog, because now I know how to use it with them. I’m planning on sprinkling the yard with it when I mow to kill off fleas and ticks. I want to keep EVERYONE pest free. Thanks for this!

  6. Thank you for spreading the news about food-grade diatomaceous earth. We use it for dusting our garden to control chewing bugs, our chickens (dusting box) to control mites and pests, around the foundation of the house to control earwigs/roaches/ants from entering the house, dust the bedding of newborn rescue kittens that can not be “flea-treated” with grown-up cat chemicals…..and so on. For those who want to live and grow plants, people, pets and productive farm animals without chemicals, this goes a long way. It is not expensive, not poison, not hard to use.

  7. I’m a bit confused. Right next to your article in my Pinterest feed is an article from The Chicken Chick about the danger of Diatomaceous Earth. She claims the dust gets in both humans and chickens lungs and causes tissue damage and eventual lung failure. And sand is your best bet for dust baths. I’d love to hear if you have reasons to disagree with her take or if maybe this is news to you too? Just want to have healthy chickens! 🙂

    1. Hi Angela, thanks for your message. There’s a lot of information on the internet, and unfortunately, not all chicken bloggers agree on certain topics. In my experience, if diatomaceous earth is used in the coop over a long period, and the chickens are left in the coop to breathe it, then it can cause problems. When we use it to clean out the coop if we’re worried about mites, we send the chickens out for a few hours (although we currently use essential oils to keep mites away instead of DE). Using DE in the open air, especially on a breezy day, shouldn’t cause issues. To help new chicken owners out (and to lower the confusion), I try to cite studies like I did in this article, so readers can know I did my homework, and that my advice comes from research recommendation. There’s a lot of proof that DE works well on external parasites, and when a chicken does come up with mites, we try to use it on breezy days to reduce the chances people or chickens will inhale it. We never apply it IN the coop – we bring the chickens to the yard for application so we can be sure the DE is applied in an open area. As for people inhaling it, if you’re consistently inhaling it, it can certainly cause an issue according to the physicians I consulted, but if you’re just using it for mite control for a brief period, it’s unlikely you’ll have issues. If you want to be super safe, you can wear a surgical mask. I’ve found that it does dry out my skin, so I wash and use moisturizer after. I hope this helps!
