Chickens, unlike most animals, do not have teeth. Instead, they need grit in their diet to help break down food in their gizzard. Grit is a collection of coarse sand, pebbles, and similar small, hard objects that chickens eat while pecking on the ground. It is essential in a chicken's diet to keep the digestive system running smoothly and ensure proper nutrient absorption. While chickens can naturally source grit from their environment, those that are confined or raised on pasture may benefit from having constant access to supplemental grit.

What You'll Learn
Chickens need grit to aid digestion
Chickens have an efficient digestive system, but unlike most animals, they do not have teeth. Instead, they need to swallow small stones, pieces of gravel, or grit to aid in breaking down their food into a digestible form. This process occurs in the gizzard, an organ found in the digestive tract of chickens that helps them grind up food.
Grit is essential in a chicken's diet to ensure proper nutrient absorption and keep the digestive system functioning optimally. Without grit, food may not break down properly, leading to blockages, poor nutrition, discomfort, and even death. Chickens that consume only commercially processed feeds, such as chick crumbles or pellets, typically do not require supplemental grit as these feeds are designed for easy digestion. However, chickens fed whole grains or treats will benefit from grit to aid in digestion.
Free-range chickens often source grit naturally from their environment by consuming small pebbles and coarse dirt while foraging. However, confined chickens or those without access to outdoor stones may require supplemental grit. This supplemental grit can be purchased from farm supply stores and is often formulated with probiotics to support gut health.
It is important to provide chickens with continuous access to grit to ensure they can eat it as needed. Chickens are intelligent and will consume grit when required for digestion. Different grades of grit are available for different ages, with younger chickens requiring a less coarse grit than adults.
Overall, grit plays a vital role in maintaining the health and well-being of chickens, ensuring they can properly digest their food and absorb necessary nutrients.

Insoluble grit is supplemental
Chickens have an efficient digestive system, but unlike most animals, they do not have teeth. Instead, they need to swallow small stones, pieces of gravel, or grit to help break down their food into a digestible form. This is where insoluble grit comes in. Insoluble grit is a supplemental grit that often comes in the form of small pieces of coarse granite or flint. This type of grit does not dissolve in the digestive system but eventually wears down and needs to be replaced with more supplemental grit in the chicken's diet.
Insoluble grit is typically made from flint or granite and is ground into tiny pieces. Chickens with access to natural sources of grit may not need supplemental grit. They can pick up tiny stones or pieces of gravel on their own, which works just as well as store-bought grit. However, if chickens are confined or unable to access grit naturally, it is important to provide them with supplemental grit.
Supplemental grit is especially important during the winter when chickens cannot access outdoor stones or pebbles. Chickens know what they need to aid their digestion, so having grit available ensures they can eat it as required. Without grit, chickens may struggle to digest larger food items, leading to blockages, illness, or even death.
Grit is essential for keeping chickens healthy and aiding their digestion. It helps break down food in the gizzard, the muscular part of a chicken's digestive tract that grinds food with muscular action. Over time, each piece of grit gets ground up, so the supply in the gizzard needs to be frequently replaced.

Soluble grit dissolves during digestion
Chickens have an efficient digestive system but they do not have teeth. To break down their food into a digestible form, they need to swallow small stones, pieces of gravel, or grit. This is where grit comes in.
Grit is essential in a chicken’s diet to keep the digestive system running smoothly and ensure proper nutrient absorption from the foods in a chicken’s diet. Food that is not broken down properly will remain in the crop or gizzard and start to ferment. Food that does not move through the digestive system properly can lead to sour crop, impacted crop, or impacted gizzard.
Soluble grit, often in the form of oyster shells, is able to be dissolved during digestion and does not supply a long-lasting source of grit. It includes shell grit or crushed oyster shell. Both offer a slow release of calcium, which is critical for bone health and strong eggshells. When chickens don't get enough calcium from their diet, they draw it from calcium reserves in their bones.
Chickens that have the opportunity to forage will naturally pick up grit from the environment to help digest fibrous plant material, making grit a normal part of chicken digestion. Oyster shell is a mineral grit that erodes less readily than other sources of calcium carbonate, letting it serve double duty as a source of both calcium for strong shells and grit for digestion. Commercially formulated rations that claim to include adequate calcium may, in fact, not provide enough for top laying hens to maintain strong bones and strong eggshells, so they require a supplemental source.

Oyster shells are a source of calcium
Chickens need grit in their diet to aid digestion. They do not have teeth, so they swallow small stones, pieces of gravel, or grit to help break down food into a digestible form. Confined chickens or chickens raised on pasture benefit from having constant access to supplemental grit. Oyster shell is a type of soluble grit that dissolves during digestion and provides calcium.
Oyster shells are a good source of calcium for chickens. Calcium is essential for laying hens as it supports eggshell quality and prevents breakage. It also helps to strengthen the chicken's bones, immune system, and cardiovascular system. Oyster shell flour is a calcium supplement that can be easily mixed into chicken food. It is a sustainable source of calcium and other minerals, and it is safe for chickens, amphibians, reptiles, mammals, invertebrates, and birds.
Oyster shell is a popular choice for chicken keepers as it is easy to administer and ensures that the chickens get enough calcium. It is also a natural source of calcium, which some chicken keepers prefer over feeding back eggshells. Some commercial chicken feed products also include calcium-rich oyster shells to ensure chickens get enough calcium in their diet.
Chicken keepers can simply leave out a bowl of oyster shells, and the hens will consume the calcium as and when they need it. Oyster shell flour is another option, which can be mixed into chicken feed to reduce waste. This is a good option for those who do not want to rely on eggshells as a source of calcium, as eggshells do not contain the same fast-release calcium as oyster shells.
It is important to note that calcium supplements are not needed until young pullets start laying. Too much calcium in a young chicken's diet can lead to kidney damage.

Store-bought grit has added probiotics
Chickens have an efficient digestive system, but unlike most animals, they do not have teeth. Instead, they need to swallow small stones, gravel, or grit to help break down food in their gizzard. Grit is essential to keep their digestive system running smoothly and ensure proper nutrient absorption. Without grit, chickens may struggle to digest larger food items, which can lead to blockages, illness, or even death.
Grit is especially important if chickens are fed treats or snacks in addition to their regular chicken feed. While chicken crumble or pellets do not require grit for digestion, as they are formulated for easy consumption, anything else they eat does. For example, if chickens have access to scratch, grains, kitchen scraps, grass, or weeds, they will need grit to aid digestion.
Chickens can naturally source grit from their environment. Free-range flocks often do not need supplemental grit since they consume small pebbles and coarse dirt when they are foraging. However, confined chickens or those raised on pasture benefit from constant access to supplemental grit.
Store-bought grit is a good option if chickens do not have access to grit from their environment. It is often formulated with probiotics (good bacteria) to support gut health and digestion, ensuring a healthy flock. When introducing chicks to grit, it is important to wait until they are around two weeks old and have started eating foods other than starter feed. At this point, they can be offered sand-size chick grit to aid digestion. Young birds can stay on grower grit until they are about two months old, at which point they can switch to adult chicken grit.
It is important to note that grit should be offered separately from chicken feed, as chickens will only eat it when they need it. Mixing small amounts of grit into their feed when first introducing it can help them discover it, but generally, they will regulate their intake. Additionally, it is crucial to ensure that the grit is not mixed with calcium supplements, as too much calcium in a young chicken's diet can lead to kidney damage.
