Have you ever wondered do chickens have teeth in their tiny beak? Maybe they don’t have teeth, or do they? Let us learn about it more and see how they manage to eat and chew if they possibly have no teeth!
A chicken is a domestic subspecies of red junglefowl, a tropical bird of the Phasianidae family. It is a very commonly recognized pet animal that has the highest population among all the birds worldwide.
Humans keep chickens as a food source in the form of meat and eggs for millennials now due to its nutritional benefits and varied cultural preferences. The expansion of the poultry farming business is at its peak due to a substantial demand for chicken meat and eggs.
However, instead of slaughtering the chicken or its overexploitation for our food requirements, many people believe that chickens are a fabulous choice as pets and prove to be our admirable companions.
If studied in detail, you’ll know that keeping chickens as your homestead pet has plenty of benefits, and that surely would widen your horizons about thinking of a chicken only as a source of meat and eggs.

Dietary Habits of Chicken
Chickens are omnivorous and can eat any edible food item or small creatures they find lying on the ground.
Their primary requirements for a nutritional diet are proteins and calcium, which keep them healthy and help them lay well-formed eggs. We can feed them with a varied range of stuff with minimal efforts and availability:
- The commercially available pellets are beneficial for essential vitamins and minerals.
- Daily leftovers from our healthy food.
- Fruits like apples, mangoes, berries, watermelon, and most of the others.
- Vegetables like leafy greens, cooked beans, corn, broccoli, cucumbers, squash, kale, beetroot, etc.
- Cereals and grains
- Insects and small animals like mice, snakes, and lizards.
Do Chickens Have Teeth?
We know that teeth are necessary for chewing food to digest it properly and assimilate the nutrients in our body in a more efficient way. It’s the first checkpoint in the gateway of the mouth, which helps to bite and break down the food into pieces for further eating process.
The majority of animals have teeth like humans, but it is different in the case of chickens. Chickens don’t have teeth; they instead have a gizzard located between the chicken’s stomach and intestines which helps in grinding and assimilation of food.
At the stage of infancy, chickens do have a tooth(called egg tooth) for a short period, which is very soft and attached to the beak of the tiny chick at the age of merely one to two weeks. It is mainly for the aid in hatching from the egg safely.
It is only there temporarily and falls off after a few days. That tooth doesn’t stay for very long or help in chewing food, so it cannot be explicitly categorized under teeth function.
How do Chickens Eat Without Teeth?
- Due to the absence of teeth, chickens cannot break down the food in their mouth. But instead, while eating, they constantly peck and smash the food against the ground to break it down into small bits. This process makes it easier for them to swallow it properly for good digestion.
- Right after the food is swallowed, it is pushed down with the tongue through the esophagus and gets stored in a small pocket located to the side of the right breast muscle called a crop. It then consists of food, water, healthy bacteria, and other necessary bodily fluids.
- The stored food is gradually passed through the gizzard towards the stomach to complete the digestion and nutrition assimilation process.
- The crop usually remains bulged throughout the day and gets emptied till the following day during the night. This procedure is the natural and healthy food cycle in a chicken resembling a good appetite and proper fecal discharge. If it is slightly mismatched or untimely for a chicken, it may signify swollen crop or crop impaction.
How do Chickens Eat their Food?
Chickens have a fantastic natural way of food consumption which eliminates many possible risks of indigestion and choking. They break down their food with their beak and eat it in large quantities enough to store in the crop.
The stored food then is digested gradually, taking a significant amount of time conveniently till the following day to avoid any complications regarding indigestion.
The female chicken, the hen, swallows tiny crumbs of food or small insects whole. If they feel that the size of food is too big for them to swallow it intact, they thrash it properly on the ground or any other complex surface to break it down into tinier pieces and then eat it.
What Is A Chickens Crop?
The chicken crop is a tiny balloon-like pouch located at the base of the esophagus and beside the right breast muscle. It acts as a storage pocket for food in a chicken’s body.
It feels soft and empty in the morning when the chicken hasn’t eaten anything, but as the chicken eats throughout the day, the crop gets plumped up and squishy due to the storage of food for later digestion.
You may feel that bulge and mistake it for a tumor in the chicken, but it’s nothing to worry about and is their natural body part.
After swallowing food, the stored food in the crop is treated internally with saliva and digestive enzymes to ensure fine breakdown and proper digestion of food along with adequate assimilation of nutrients.
In case the crop of the chicken feels hard on the touch, and the swelling doesn’t reduce overnight, this may be an abnormal situation, possibly causing crop impaction, which means that the food material is stuck in the crop.
Contact your vet immediately if this happens and take their assistance.
What Is A Chicken’s Gizzard?
The gizzard is a digestive organ in a chicken’s body that helps to process the food and grind it properly. The proventriculus and gizzard both collectively form a chicken’s stomach.
When the food passes through it on its way to the proventriculus, the small stones or grit supplementarily aid in the digestion process. Meanwhile, muscular contractions occur in the digestive tract before entering the intestines.
The slight muscle contractions employed by the gizzard against the grit help churn the food and pass it further into the intestines for easy digestion.
The gizzard is basically the substitute organ for teeth in chickens which carry out the food grinding process similar to the teeth.
Why Do Chickens Need Grit?
Chickens need to be fed grit to ensure the proper breakdown and grinding process of food in their body. It is beneficial for their digestive health and assists in mineral and calcium intake.
Pet owners sometimes ignore to feed grit to their chicken, assuming they will have it themselves while roaming free all-around the verandah.
It is your responsibility to feed them grit in your presence to ensure that the digestion runs smoothly and you won’t have any problems regarding chicken’s health.
Your chickens may not find enough grit when pecking the whole farm and suffer improper digestion leading to digestive issues and fatal health problems. So, remember to keep the grit accessible to them to ensure optimum health.
It is necessary to sprinkle the grit in the chicken coop and all around the enclosure to keep it available for them in the required amount. Chickens know the importance of grit and will search for it whenever they feel the need.
The teamwork of gizzard, food, grit, and crop to ensure complete digestion and nutrient assimilation in chickens is the most crucial process of their body for achieving healthy growth.
There are two types of grit available commercially:
Ground oyster shell grit – It is suitable for providing necessary calcium, but if fed in more amount, it could cause the shells of the chicken’s eggs robust in nature. Its recommended not to go for this grit as it doesn’t specifically improve digestive health.
Flint grit – It is derived from powdered granite and is relatively insoluble, which will help in proper digestion by staying in the gizzard for quite a long time.
Can Chickens Grow Teeth?
No, chickens don’t tend to grow or develop teeth. However, in conjectural research, scientists found that in the stage of embryonal growth in a mutant chicken, the beak had minuscule ridges and bumps resembling alligator-like teeth on the edges.
But the genetic mutations in the species for decades made it impossible for the teeth to develop substantially. All known birds have lost their ability to grow or develop teeth for ages apart from this discovery regarding chickens.
The genetic development in a species or genus is biologically confined to inherit specific robust traits from their previous generation to form a set of essential characteristics in the creature.
This exception makes it nearly impossible for birds or chickens to develop teeth if their previous generations missed those traits and failed to inherit them from older generations or possibly diminished the inheritance gradually.
Chicken Breeds with Teeth
There are no records of any birds or breed of chicken having teeth on Earth at present. Chickens only develop a temporary egg tooth in their infancy to assist in the hatching process, which falls off in a few days.
Apart from the present creatures or birds, the ancient prehistoric birds have developed teeth entirely like a carnivore and were of species closest to a bird.
Dinosaurs or seabirds like Pelagornithidae, Archaeopteryx, Sapeornis, and Confuciusornis were proficient in flight and had teeth.
What do Chickens Eat in the Wild?
Chickens inhabiting the wild rely on insects and small rodents for their dietary requirements. The insects include termites, a variety of ants, earthworms, and other crawly buddies.
They have excellent eyesight and fast speed, which help them prey on termites and ants, providing a source of high protein and fats from a minuscule amount.
Many of the birds and wild fowls fulfill their daily nutritional requirements feeding on these insects and invertebrates.
Apart from the carnivorous diet, a wide variety of foraged plants, fruits, edible leaves, and other safe green shrubs are also subsequently available in the jungle to fulfill the dietary needs of wild chickens.
The environment in which the jungle fowl live is varied from place to place depending on the climate, vegetation, and wildlife.
According to the conditions that favor the jungle in the situation, the domination of food availability will be affected by changing the specific dietary preferences of the wild chicken.
For example, Red jungle fowls like to eat the bamboo seeds whenever available; they scratch the whole stem until they get to the seeds and eat them.
What is Chickens’ Favorite Food?
Chickens tend to have different preferences individually, but if narrowed down, they enjoy:
- Insects – Mealworms
- Veggies – Lettuce, turnip greens, kale, beetroot, broccoli, pumpkins, cucumbers, carrots, and chard
- Fruits – Strawberries, blueberries, watermelon and pineapple.
- Herbs – Mint, parsley, cilantro, thyme, oregano, basil, and lavender
- Perrenials – Roses, coneflowers, ferns, lilies, daisies, and hostas
Chickens find it interesting to forage the garden on their own to see their favorite food.
So, build a unique garden for your chicken with fences and tunnels to have their regular foraging sessions and walks.
Plant their favorite herbs, veggies, and edibles in the park for them to pluck and eat.
What Chickens Should not Eat?
The dietary intake of the chicken affects the quality and taste of the egg the lay. Feeding chickens some offbeat and aromatic solid ingredients like garlic, ginger, and onion are highly prevalent and could negatively affect the egg’s quality.
Several other toxic ingredients are not suitable for chickens to eat and possibly cause indigestion, gastrointestinal problems, and other fatal disorders.
- If you feed them with your leftover food items, make sure they aren’t very moldy, rotten, or highly salted because it is very poisonous and can cause severe indigestion resulting in moist feces and possible death.
- Dried or undercooked beans contain a chemical called hemagglutinin, which severely affects digestion in the chicken that could last for days.
- The peels and pits of avocado contain persin, which has poisonous effects on chickens. You can instead need them the flesh of an avocado.
- Rhubarb plant has anthraquinone present in it, which has a laxative effect. Moreover, the high oxalic acid content could be lethal for chickens.
- Beverage ingredients like alcohol, caffeine, and chocolate are also toxic to chicken and could cause electrolyte imbalance, heart failure, and obesity due to high salt and sugar contents.
- Some peels and leaves of veggies like tomatoes, peppers, and potato peel are poisonous and are best if avoided.
Your chicken should have access to a limited and moderate amount of food every day to ensure a balanced diet, maximal nutritional benefits, and prevention of overfeeding, which may also be fatal.
Set a proper diet routine of a strict dietary baseline and special treats for your chicken of different varieties.
How Much do Chickens Eat per Day?
The amount of food consumption in a chicken usually depends on age. The feeding frequency may vary according to the individual. We must adequately create a dietary routine to provide a balanced and nutritious diet in a specific limited amount of food.
Adult – We should feed up the egg-laying adult chicken 4 ounces a day.
Infants (first few days) – Half an ounce per meal with a frequency of 10 to 12 meals a day.
Babies (after one week) – 1 to 2 ounces per meal with a frequency of 10 to 12 meals a day.
Chicks (after two weeks) – 2 to 3 ounces per meal with a frequency of 10 to 12 meals a day.
Do chickens even have teeth?
No, chickens don’t have any teeth and instead have gizzards to help in chewing and grinding food.
How does chicken chew their food?
Chickens chew their food by thrashing it against the ground with their beaks so that it breaks down to fine crumbs and then swallow it intact, storing it in the crop, which then eventually gets gradually digested in a day.
Do all chickens have an egg tooth?
Yes, when the chicken is in the stage where it would hatch soon from the egg, it develops an egg tooth that stays only for one to two weeks until it is used to crack the egg and hatch out safely.
