"The chickens don't even notice that anything has been added to the food - but over time, you can definitely see the difference. Firmer egg shells and more vibrant coloring on the combs are probably the two most obvious."

"I'm really loving this product. I've noticed significantly cleaner booties since I've introduced this into their feed."

Two scoops (2 tablespoons) on the feed once a day for every 5 hens. Big feeder? Mix 1 pouch into each 50 lb bag of feed.
Yes. It's natural and non-medicated, so there's no egg withdrawal.
No. It's a daily digestive supplement, not a medicine, and it won't clear an active infestation. If a bird is sick, see your vet. Peck Purity is the everyday part.
Most keepers notice firmer droppings and cleaner eggs in the first couple of weeks. Every flock is different.
One pouch covers 4–8 hens for about a month. The pack picker above matches pouches to your flock size.

The Problem
Most keepers see these signs and treat each one on its own. But they usually aren't four different problems. It's one problem showing up in four different places.

Crusty, matted feathers under the tail and eggs you have to scrub. When the gut isn't firming droppings up, the mess ends up on her and in the nest box.

Wet splats on the roost board and soggy bedding. Loose droppings mean feed is rushing through before her body can use it.

Feathers are almost pure protein. If she isn't getting the most out of her feed, regrowth drags and her coat stays thin and ragged.

Making an egg takes a huge amount of protein and calcium. When her gut is struggling, laying is the first thing her body cuts.
All four of these trace back to one thing. The gut.
Support her gut every day and the outside follows: cleaner vents, firmer droppings, a fuller coat and a flock that looks and feels its best.
The Solution
Made for flocks dealing with messy vents, runny droppings and the gut troubles behind them. Formulated by a Doctor in Poultry Nutrition, built on ingredients with published poultry research and made in the USA.

Created by a poultry nutrition expert specifically for the backyard hen's gut.
Every key ingredient was chosen because peer-reviewed poultry studies stand behind it. The studies are cited below.
Natural and non-medicated. No chemicals and no egg withdrawal, so you keep collecting and eating your eggs.

I've got 30 chickens so I make 2 treat pans for them with Peck Purity on top and they can't get enough. Their poops are firm and their vents are almost sparkly clean! I give that credit to Peck Purity, love this product!

Each ingredient has a job. Here's what they do and the research behind them.
Peck Purity is made with food-grade diatomaceous earth, the backbone of the blend. In a study of free-range laying hens, hens fed diatomaceous earth carried lower internal parasite loads than hens on normal feed. A dewormer is a few days of treatment, and then she's right back on the same ground she picked the worms up from. Peck Purity is daily gut defense that helps protect her gut every single day.
The research: Bennett et al., Poultry Science, 2011.
Peck Purity is made with yucca. Coccidia are tiny gut parasites, too small to see, and they live in the dirt of almost every chicken run. In a study of 504 birds, the birds that ate yucca had less than a quarter as many coccidia as the birds that didn't.
The research: Animals, 2022.
A balanced gut decides how much of her feed she actually uses. Yucca supports gut balance, diatomaceous earth supports a clean digestive tract, and the plant protein adds a little extra protein to every scoop. Plus, hens love the taste. The first thing keepers usually notice is firmer droppings.
Shells need calcium and feathers are almost pure protein, and both get pulled from the feed through the gut. When digestion is steady, more of what you already feed goes into clean, strong eggs, bright combs and a full, glossy coat after molt.
What keepers say: "Firmer egg shells and more vibrant coloring on the combs." – Elizabeth T.

The base of the blend. Daily support for a clean, healthy digestive tract.
