Best Grit For Chickens

The best grit for chickens is vital for your birds’ digestive system to work well. Adding grit to poultry feed helps food to grind down in the gizzard and keeps your chickens happy. If you keep chickens in a coop or fenced enclosure, it’s advisable to add grit to their diet to ensure the birds get enough to aid healthy digestion.

Various types of grit are available to supplement the diet of backyard chickens. For laying chickens, the grit should contain calcium that aid in egg production. However, for non-laying chickens, crushed granite or sand is ideal because they don’t need calcium supplements. Chickens—including free-range ones—consuming grains, grass, and weeds need grit in their diet.

Frequently asked Questions

What is chicken grit, and what is in it?

Chicken grit is crushed stones that promotes healthy digestion in birds. As with all birds, chickens don’t have teeth. This means that they consume chicken feed and grains without chewing their food. The tiny bits of stone grind up feed as the gizzard’s muscles contract.

Why is it important to give your chickens grit?

Grit is essential in a chicken’s diet. Without grit, chickens would suffer from discomfort, digestive problems, low nutrient absorption, and even death. Backyard chickens don’t always have access to grit in their coop or chicken run. So, giving your chickens grit is one way to keep them healthy.

How to give my chickens grits?

There are two ways to give your chickens grit. First, you can add grit to their feed, and they will consume it along with grains and chicken feed. Secondly, you can use a separate feeder for giving chickens grit. They will peck as much as they need.

Can chickens eat too much grit?

No, it’s impossible to give chickens too much grit supplements. To care for chickens properly, give them free access to grit. The birds will then take what they need to digest food. A seven-pound bag of grit should be enough to last a small flock of chickens for up to 12 months.

How often do I feed my chickens grit?

Chickens need constant access to grit to keep their digestion healthy. So, you should regularly check their feed and ensure they’ve always got an adequate supply of good quality chicken grit.

Do you mix grit with chicken feed?

Mixing grit with chicken feed is one way to ensure they get enough in their diet. However, most chicken owners use a separate grit feeder for their brood. Or, you can scatter grit on the ground for your chickens to peck as they need.

At what age do I start giving my chickens grit?

Chickens need grit from about two weeks old. Ensure that the kind of grit you give baby chickens is “chick grit.” This is finely-crushed gravel that is suitable for chicks. After chickens are about eight weeks old, you can switch to regular chicken grit to help keep their digestive system working correctly.
