All stages — the cross-cutting one
Chickens manage their own parasites given somewhere dry to roll in. Providing that is close to free and it is the highest-return thing on this hub.

The short answer
A dust bath is dry loose material a chicken can roll in — soil, sand, wood ash, optionally food-grade diatomaceous earth. The dust works into the feathers and abrades or smothers external parasites. The only requirement that genuinely matters is that it stays dry, because wet dust does nothing at all.
Dust bathing is instinctive, not learned, and it is not play. A chicken scratches a hollow, settles into it, and flicks material up into her feathers with her wings, then shakes it out. The dust works down to the skin, absorbs excess oil, and abrades or smothers mites and lice living there.
It is the flock’s own parasite management and it works. A flock with permanent access to a good dry dust bath has a meaningfully lower parasite burden than one without, and providing it costs almost nothing.
It is also the reason chickens dig craters in your flower beds. If you do not provide a bath, they will find one, and it will be somewhere you would rather they did not.
| Ingredient | Role | Notes |
|---|---|---|
| Dry soil or sand | The base; most of the volume | Whatever you have. Sand drains and stays loose |
| Wood ash | Fine, alkaline, absorbs oil | Untreated wood only. Never briquettes or treated timber |
| Food-grade diatomaceous earth | Abrasive; the parasite-specific ingredient | A modest proportion, mixed through. Mask up when mixing |
| Dried herbs | Nothing we can substantiate | Harmless; the claims are not sourced |
| Peat or dry compost | A soft base some keepers prefer | Must be genuinely dry |
There is no correct recipe and we are not going to invent proportions to sound authoritative. The base is dry loose material; the additives are optional. The most common practical mix is roughly equal parts dry soil and sand with wood ash and a smaller proportion of DE worked through.
Every component of a dust bath works by being a dry loose powder that gets into feathers. Wet, none of it does. Damp DE is inert; damp ash is a paste; damp soil is mud, and a bird rolling in mud is worse off than one that did not.
So siting matters more than the mix does. Under a raised coop, inside a covered run, or under any shelter that keeps rain off. If your only option is open ground, use a container with a lid you can put on when it rains.

The base is dry soil or sand you already have. These are the two things worth buying, and only one of them is essential.

89%+ silicon dioxide, OMRI
Eighty-nine percent silicon dioxide, OMRI listed, and honest about what it is for — a dusting powder for the places birds bathe, not a treatment for an infestation you already have.

Triple-screened, 99% dust-free
Ordinary pine shavings with an unusual claim attached: triple-screened to 99 percent dust-free, which is the one bedding spec that matters in an enclosed brooder.

A base of dry soil or sand, optionally with wood ash from untreated wood and a modest proportion of food-grade diatomaceous earth mixed through. There is no single correct recipe; the base is most of the volume and the additives are optional. Keeping it dry matters far more than the exact mix.
They will make one whether or not you provide it, because dust bathing is instinctive rather than learned. Providing a good dry one gives you the parasite-prevention benefit and saves your flower beds. A flock with permanent access to a dry dust bath carries a meaningfully lower parasite burden.
Roughly two feet square and four to six inches deep for standard breeds — big enough for a bird to lie down and flap in, and low enough to step into easily. Too small and the birds will use it briefly and then dig a proper one somewhere you would rather they did not.
Yes, from untreated wood only. It is fine, alkaline and absorbs oil, which is exactly what a dust bath is for. Never use ash from charcoal briquettes, which contain binders and accelerants, or from treated, painted or engineered timber.
