What Keepers Notice After Adding Peck Purity

4.7 out of 5from 140 verified Peck Purity reviews
"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."
Elizabeth T. Verified Buyer
"My chickens were having watery poops who knows what they got into being free range... The watery poop has stopped, and I am continuing to use this product every day."
Anna V. Verified Buyer

Quick Questions

How do I use it?

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.

Can I still eat the eggs?

Yes. It's natural and non-medicated, so there's no egg withdrawal.

Is it a dewormer?

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.

How soon will I see a difference?

Most keepers notice firmer droppings and cleaner eggs in the first couple of weeks. Every flock is different.

How long does a pouch last?

One pouch covers 4–8 hens for about a month. The pack picker above matches pouches to your flock size.

Can I cancel or get a refund?

Skip, pause or cancel your subscription anytime. Every order has a 90-day money-back guarantee.

The Problem

Common Signs Of Hidden Flock Problems

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.

Hen with a dirty, matted vent

Dirty Vents & Poopy Eggs

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.

Watery droppings on the coop floor

Watery, Runny Droppings

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

Hen with rough, thin feathers

Rough Feathers & Slow Molt Recovery

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.

A single egg in the nest box

Fewer Eggs In The Nest Box

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.

4 Things Peck Purity Does For Your Flock. Every Day.

Each ingredient has a job. Here's what they do and the research behind them.

01

Everyday Gut Defense

Diatomaceous EarthEvery day, not a 5-day treatment

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.

02

Coccidia Support

Yucca SchidigeraNatural plant saponins

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.

03

Digestion & Gut Health

YuccaDiatomaceous EarthPlant Protein

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.

04

Egg Quality & Feather Condition

Cleaner eggsStronger shellsMolt recovery

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.
