She Eats. They Eat First. And The Gut Wall Takes The Damage.

Intestinal parasites live in the gut lining — the same surface that absorbs everything she eats.

Feeding and burrowing flattens it. A flattened gut absorbs less, and the inflammation that follows makes digestion less orderly.

So she gets less from the same feed, and what passes through is wetter. Between them, those two explain nearly every mess.

One Root. Six Different Messes.

Trace them back and they keep arriving at the same place.

Each one has its own aisle at the feed store, and its own weekend routine.

01Watery droppings

A damaged gut lining absorbs less water back out. More goes straight through.

02The caked vent, the pasty butt

Loose droppings don’t fall clear. They catch, dry, mat, then catch the next lot.

03Dirty eggs

The egg passes the vent on the way out. The nest box was never the problem.

04Thin, dull or missing feathers

Feathers are nearly all protein. A higher-protein feed can’t help if absorption is the bottleneck.

05Fewer eggs

An egg is built fresh daily, and it is the first line cut when there is a shortfall.

06The quiet hen

Less energy reaching her, and an immune response running in the background. Noticed last, almost always.

One problem, surfacing in six places. Which is why the ones you fixed last month are back this month.

Researchers Tested 64 Backyard Flocks With No Signs Of Disease. 64% Had Coccidia.

A 2021 survey of backyard flocks in the United States.

Not one looked sick. About 1 in 4 also had Capillaria, and 1 in 5 had roundworms.

A healthy-looking hen is not proof of a healthy gut. Nobody knew, because roundworm eggs are too small to see without a microscope.

It is also why the usual fixes never hold. A bath cleans the outside. A better pellet changes what goes in, not how much she keeps.

Every flock that touches dirt gets exposed. You cannot stop that. You can defend her gut daily.

You Can’t Stop Her Picking Them Up. You Can Defend Her Gut Every Day.

She could pick up new gut bugs every day she pecks the ground. So the answer has to be daily.

Peck Purity is a daily gut defense. Every scoop has two natural ingredients that scientists have tested on chickens.

Peck Purity was formulated by a doctor with a PhD in poultry nutrition, around two ingredients with published research in chickens.

In one study, chickens with coccidia that ate yucca ended up with almost 6 times less infection.

In another, hens fed food-grade diatomaceous earth every day finished with fewer parasites.

One scoop on the feed. No syringes, no catching birds, no egg withdrawal.

This is the daily part, not the emergency part. It will not clear an active infestation — that is a vet. A visibly unwell bird is a vet today.

Common Questions

Let's clear this up before you order.

No. Peck Purity is a non-medicated feed supplement, not a medication — you keep collecting and eating eggs the whole time.

Give it about two weeks of daily feeding before you judge it. It's gradual, not dramatic — and it works the way a daily habit works, which means it only keeps working if you keep doing it.
