Why Chickens Need Grit: The Ultimate Guide to Types of Grit for Your Flock
If you’ve ever watched a flock pecking around the yard, you’ve likely noticed them swallowing small rocks or grit. But have you wondered why chickens need grit? It’s a vital component of their digestive process, helping them turn hard, indigestible food into the nutrients they need to stay healthy and active. In this guide, we’ll explore the different types of grit, why it’s essential, and how to provide the right grit for your feathered friends.

What Is Grit and Why Do Chickens Need It?
Grit is small, hard particles—such as stones or oyster shells—that chickens swallow to aid digestion. Their gizzard, a muscular part of their stomach, grinds the food with the help of these particles, breaking down seeds, grains, and other tough foods. Without adequate grit, chickens may struggle to digest properly, leading to health issues and reduced egg production.
The Types of Grit for Chickens
Not all grit is created equal. There are different types suited for different purposes. Let’s break them down:
Inert Grit
What it is: Typically made from natural stones or crushed rock that doesn’t dissolve.
Purpose: Primarily used to grind food in the gizzard. It aids digestion without adding nutrients.
Examples: Granite, flint, or crushed rock.
Oyster Shell Grit
What it is: A soft, calcium-rich material derived from crushed oyster shells.
Purpose: Provides calcium for strong eggshells and bone health.
When to use: Ideal for laying hens and during peak egg production.
Crushed Eggshells
What it is: Clean, crushed eggshells from your kitchen waste.
Purpose: An affordable, natural source of calcium to support eggshell formation.
Note: Should be cleaned and crushed finely to prevent suffocation risks.
How to Choose the Right Grit
Understanding your chickens’ needs is key:
For free-range chickens: They often find their own grit, so supplemental grit isn’t always necessary.
For penned or indoor chickens: Providing an appropriate grit source is essential.
For layers: Incorporate oyster shell grit to maintain strong eggshells.
When and How to Provide Grit
Grit should be offered as part of your chickens’ diet in moderation:
Hanging or free choice: Place grit in a feeder where chickens can access it freely.
When to supplement: Especially when introducing new foods or if your chickens are kept in confinement.
Important: Never give grit to chicks under 8 weeks old, as their digestive systems are still developing.
Common Grit Mistakes to Avoid
Using the wrong grit for the age: Chicks and young birds need only inert grit; oyster shell grit can be added for layers.
Over-relying on grit as food: Grit is a digestive aid, not a food source. Ensure your chickens have a balanced diet.
Neglecting calcium needs: Layers require additional calcium through oyster shell grit to support eggshell quality.
Providing the right type of grit is a simple yet crucial step in maintaining a healthy, productive flock. Think of grit as the little aid that helps chickens turn their everyday feed into the nourishment they need to lay eggs, stay energetic, and thrive. So next time you’re preparing their feed, remember: a well-fed chicken is a happy chicken—thanks in large part to the humble grit.
