What is Chicken Grit? and Why It is Important?

Have you ever watched chickens peck at bits of rock and sand? This isn’t just random behavior—it’s a critical part of their diet called “chicken grit.” Grit plays a huge role in helping chickens digest their food properly.

When I started raising chickens, I thought feed and water were enough. But soon, I noticed some digestion issues in my flock. That’s when I learned about the magic of grit! Those tiny stones act like mini grinders, helping chickens break down food.

Adding grit made a big difference in my flock’s health. It’s amazing how such a small addition can have such a big impact.

In this post, we’ll explore what chicken grit is, why it’s essential, and how to choose the best kind for your birds.

Key Takeaways

Grit is essential for digestion – Chickens lack teeth, so grit in the gizzard helps break down food for proper nutrient absorption.
Two types of grit serve different roles – Insoluble grit (granite) aids digestion, while soluble grit (oyster shells) provides calcium for strong eggshells.
Chicks may not need grit immediately – If eating only starter feed, they can digest food without it. Grit becomes necessary once they start eating grains or foraging.
Chickens regulate their own grit intake – Providing grit in a separate dish allows them to consume it as needed, preventing digestive problems like sour crop or impacted gizzard.
Diet impacts grit needs – Free-range chickens naturally pick up grit, but those on a grain-based diet or commercial feed require supplemental grit for optimal digestion.

1. What is Chicken Grit, and Why Does It Matter?

Chicken grit, or poultry grit, is made up of tiny, coarse bits of stone or gravel. These little stones are crucial for chickens’ digestion, as they lack teeth to break down food.

When a chicken swallows food, it heads to the crop—a temporary storage area. Here, grit starts the job of breaking down tougher bits before food continues to the gizzard. This strong, muscular part of a chicken’s stomach acts like nature’s blender.

In the gizzard, grit and strong muscles work together to grind food into a digestible mush. Enzymes then join in to help break it down further, allowing essential nutrients to be absorbed as it moves through the intestines.

Without grit, food can get stuck, leading to sour crops or impacted gizzards. By adding grit, chickens can digest efficiently, keeping them healthy and helping them get the most nutrients from their diet.

In short, grit is tiny but mighty, ensuring smooth digestion and nutrient absorption!

2. Different Types of Chicken Grit

There are two common types of grit you’ll hear chicken keepers refer to.

Insoluble grit and Soluble grit.

2.1 Insoluble Grit

Insoluble grit is made up of hard stones, like granite, that chickens consume but can’t digest. This grit stays in the gizzard, helping grind down hard foods like grains, seeds, and insects. It’s like a permanent tool in their digestive system, aiding in smooth digestion by acting as a grinder for tougher foods.

2.2 Soluble Grit

Soluble grit, often made from crushed oyster shells or limestone, provides calcium to chickens, especially laying hens. Unlike insoluble grit, this type dissolves in the digestive system. Calcium from the grit strengthens eggshells and promotes overall bone health in chickens.

2.3 When to Use Each Type of Grit?

Chicks and young chickens mainly need soluble grit to support their growing bones. For adult chickens, especially those with a diet rich in grains, a mix of both insoluble and soluble grit ensures a healthy digestive system and strong, sturdy eggs.

3. The Science Behind Chicken Grit and Digestion

Chickens have a fascinating digestive system that’s built around the need for grit. Unlike us, they don’t have teeth to chew their food. Instead, they rely on a unique combination of their crop and gizzard to handle digestion.

When a chicken eats, food first travels to the crop. The crop is a small “storage pouch” that temporarily holds food right after eating. This pouch lets chickens eat more at once, saving some food for later digestion.

In the crop, insoluble grit starts breaking down tougher bits of food. The grit acts as the first tool in the chicken’s digestion, softening hard pieces before food moves to the next stage.

After leaving the crop, food travels to the stomach, where enzymes start breaking it down further. This enzyme activity is important for preparing food for deeper digestion and nutrient release.

Next, food reaches the gizzard, which is a powerful, muscular organ. The gizzard acts like a mini grinder, with grit and strong muscles working together to crush food into a soft mash.

This grinding process in the gizzard is essential. It lets chickens access nutrients from grains and seeds that would otherwise pass through undigested. Without grit, they would miss out on much of their food’s value.

In short, grit keeps chickens healthy by preventing digestive issues like sour crop or impacted gizzard. It’s nature’s way of helping chickens get the most from their meals and stay in top shape!

4. Do All Chickens Need Grit?

Yes, most chickens benefit from grit, but their needs vary. Chickens that roam outdoors and peck at the ground naturally find grit like small stones, fulfilling their digestive needs. However, chickens kept in coops or on commercial feed often require supplemental grit.

For young chicks, grit is usually not necessary, especially if they’re eating soft starter feed. As chickens grow and eat whole grains or tougher foods, adding grit helps them digest properly.

In short, providing grit depends on diet and lifestyle, but it’s essential for adult, grain-fed chickens.

5. How to Choose the Right Chicken Grit?

Selecting the right grit for your chickens ensures they get the digestive support they need for a healthy, balanced diet.

Consider the Age of Your Chickens: Chicks don’t usually require grit if they’re on a soft starter feed. However, as they grow and start eating grains or harder foods, providing grit becomes essential for their digestion and overall health.
Choose Between Insoluble and Soluble Grit: Insoluble grit, (such as granite), stays in the gizzard and helps grind up food. Soluble grit, (like crushed oyster shells), dissolves in the system and supplies calcium, which is especially beneficial for egg-laying hens.
Look for the Right Size: Young chickens need smaller-sized grit, as their digestive systems are still developing. For adult chickens, a larger grit size is more effective, ensuring that food is properly broken down and digestion runs smoothly.
Match Grit to Their Diet: Chickens eating mostly commercial feed may require less grit compared to those on a diet of whole grains. Adjust the type and amount of grit based on the specific foods your flock regularly consumes.

6. When and How Much Grit Should You Offer?

6.1 When to Start Offering Grit to Your Chickens?

For Young Chicks: Chicks typically don’t need grit if they’re on starter feed, which is soft and easy to digest. If chicks start eating grains or treats, introduce grit around 3-4 weeks old to support digestion.
For Adult Chickens: Grit should always be available for adult chickens, especially if their diet includes grains, seeds, or if they’re free-ranging. Regular access to grit helps ensure proper digestion as they consume a more varied diet.

6.2 How Much Grit Should Chickens Consume?

Self-Regulation: Chickens are naturally good at regulating their grit intake and will consume it as needed when it’s available.
Provide a Separate Dish: Place a small dish of grit in their coop so they can access it freely, taking only what they need.
Laying Hens and Soluble Grit: Laying hens may consume more soluble grit, such as oyster shell, to meet their calcium needs for stronger eggshells.
General Guide for Insoluble Grit: For insoluble grit, a handful every few weeks is generally sufficient, as long as chickens have consistent access to it in their space.

6.3 Best Practices for Offering Grit

Place grit in a separate dish to keep it clean and easily accessible, allowing chickens to consume it on their terms. Avoid mixing grit directly into feed, as chickens may end up eating too much grit or not enough, depending on their individual needs.

7. Frequently Asked Questions About Chicken Grit

What is in Chicken Grit?

Chicken grit is made up of small, coarse particles like crushed granite or oyster shell. Granite grit provides a permanent grinding aid in the gizzard, while oyster shell grit dissolves and supplies calcium for laying hens.

At What Age Do Chickens Need Grit?

Chickens typically need grit when they’re around 3-4 weeks old, especially if they start eating grains or treats. Young chicks on soft starter feed may not require grit right away, but it’s essential as they grow.

How to Make Your Own Chicken Grit?

You can make chicken grit by crushing clean, hard stones or seashells into tiny, digestible pieces. Just be sure they’re free from contaminants and sized appropriately for your chickens’ age and needs.

Is Chicken Scratch the Same as Grit?

No, chicken scratch and grit are different. Chicken scratch is a treat made up of grains like corn, oats, or wheat, while grit is a digestive aid, helping chickens grind and break down food in their gizzard.

Can Chickens Eat Without Grit?

Chickens on a commercial feed diet may digest fine without grit, as the feed is soft. However, chickens eating grains, seeds, or foraging outdoors absolutely need grit to properly digest tougher foods.

What Food Makes Chickens Grow Faster?

High-protein feeds, such as starter or grower feed, promote faster growth in young chickens. Additionally, foods like mealworms and other protein-rich treats can supplement growth, but grit is necessary for digesting these foods.

Difference Between Chicken Grit and Feed?

Chicken grit is made of non-digestible particles that help break down food in the gizzard, while feed is the actual food source providing essential nutrients. Grit aids digestion, allowing chickens to absorb more nutrients from their feed effectively.

8. Wrapping It Up

Grit may seem like a small detail in chicken care, but it’s a crucial part of keeping your flock healthy and thriving. From supporting digestion to aiding nutrient absorption, grit plays a big role in your chickens’ daily lives.

By understanding the different types of grit, when to offer it, and how much your chickens need, you’re giving them the best tools for a smooth digestive process. Remember, whether they’re free-ranging or living in a coop, grit ensures their diet is balanced and well-digested.

Offering the right grit to your chickens helps prevent digestive issues like sour crop and impacted gizzard, keeping them comfortable and happy. With just a small addition to their routine, you’re supporting a healthy, contented flock that’s ready to produce quality eggs and grow strong.
