How Much Grit Does A Chicken Need?

A chicken eats a small amount of grit compared to feed. Generally, it is 1/20th of their diet.

For example, if a bird eats around 1.75 pounds of feed weekly, it will need approximately 0.0875 pounds of grit.

However, the amount can be a bit higher if chickens eat foods that are hard to digest.

Larger chooks may need more grit as they eat more food than bantam chickens.

The simple rule is feeding enough grit to fill their gizzard to digest the food comfortably and easily.

Do Chickens Need Grit Every Day?

Feeding chickens grit daily is necessary as chickens eat a wide range of food daily.

Whether they eat clumps of grass, dandelions, worms, or treats, chooks need to eat grit regularly. After all, they don’t have any teeth like humans.

You should serve the grit separately as a free choice next to their feed. They will feed as much as they need.

Flocks are less likely to overeat these hard substances as they don’t enjoy eating them like other food.  

What Type Of Grit To Feed Chickens?

You want to feed them chick grit during the first eight weeks of age. This type of grit is smaller and softer to eat easily.

Their hardness level is lower to keep the gizzard and digestive system safe.

But when chickens exceed 8 weeks, you can start feeding them adult chicken grit. Their hardness is a bit higher to break down the feed quickly.  

How To Choose A Grit For Chickens?

Best Grit For Chickens

01. How Old Are Your Chickens?

One of the most important aspects is considering your chicken’s age before choosing a particular grit.

Smaller and finer grits are better for younger chickens. This allows them to easily digest the feed.

But larger and coarser grits are better for adult chickens. This type of grit has a higher hardness level to process hard-to-digest food easily.

02. What Type Of Feed do You Serve?

Another critical factor is what type of chicken feed you regularly serve your flocks.

If your feathered friends eat a good amount of whole grains or scratch grains, feeding them enough grit is essential.

Otherwise, their body will struggle to absorb nutrition from the food.

The importance of grit will be lower if your birds eat commercial feed. This type of feed already has smaller particles.

03. What Kind Of Grit To Feed Chickens?

Chicken grits are available in various types, such as granite, oyster shell, insoluble crushed rock, etc.

If you want to help your hens to develop strong eggs, Oyster shell grits are the best choice. It is rich in calcium.

However insoluble crushed rock grit is the most widely used option as it serves all purposes.

Many of them contain probiotics to improve the digestive health of the chickens by breaking down the feed in their gizzard.

04. How Many Chickens Do You Have?

Each chicken needs grit daily. Make sure to buy in bulk to avoid getting finished quickly. Also, you will save a few bucks.

But how much to buy at a time, right? Generally, a chicken is likely to eat an average of 0.0875 pounds of grit per week.

The table below shows how much 10, 20, 30, 40, and 50 chickens will need weekly and monthly.

05. Does The Grit Have Any Chemicals Or Contaminants?

Make sure to choose natural-based grit that contains no chemicals, additives, or contaminants.

Also, it needs to be free from soy and corn as they may disrupt the breaking down functionalities of these small pebbles.

In addition, choose grits that don’t have any artificial colors and preservatives. They can harm chickens’ overall health if chooks eat them regularly in the long run.

06. How Much Are You Ready To Pay?

Chickens eat a minimal quantity of grit daily. But they are relatively more expensive than chicken feed.

Their average price can be $2 to $3 per pound. There are some premium options too. Plus, their cost can be more than $5 per pound.

Before choosing a particular option, compare the cost and benefit. You should also consider your budget as you will feed them in the long run.

Avoid shifting from one brand to another. Chicken may show unwillingness to eat a new brand as they are already used to the existing one.

Changing the container and placing it in another location may also help.

Make sure the container doesn’t stay empty for hours. Flocks need to eat these small pebbles after finishing their meals.

04. Clean The Container

Grit containers may become dirty over time. Chickens may poop on them sometimes.

Make sure to clean the pot regularly. Avoid feeding them dirty grit. Clean the tiny stones if they are dirty.
