Chickens are omnivores and in their natural environment, they eat insects and meat. However, some companies advertise that their chickens are fed vegetarian diets, which is appealing to consumers. While this eliminates the potential disease risk of animal by-products, chickens on a vegetarian diet can become deficient in the essential amino acid methionine, which can cause them to become extremely sick and aggressive towards each other.

Chickens are natural omnivores and need meat and insects in their diet to be healthy
Chickens are natural omnivores and need a balanced diet that includes meat, insects, and plants to stay healthy. While chickens can eat almost anything, they are particularly fond of variety in their diet. They are known to enjoy meat, insects, and plants, and will happily feed on a range of different foods.
In the wild, chickens are scavengers and will hunt for insects like beetles, grasshoppers, ants, worms, and other small creatures. They will also eat plants, flowers, and seeds. Chickens are often kept as pest control because they will eat almost any insect, including grubs and larvae, flying and crawling insects, and even scorpions. They will naturally avoid stinging insects like wasps and bees, but they will eat honey bees. It is important to note that chickens should not eat insects in areas where herbicides and pesticides have been used, as these chemicals can be harmful to their health and affect egg production.
Meat is also a natural part of a chicken's diet. They will eat meat from earthworms, snakes, mice, lizards, and even small frogs. Chickens can also be fed meat scraps, and this was a common practice before commercial poultry feed was readily available. While some people are uncomfortable with the idea of feeding meat to chickens, it is a healthy part of their diet and will not affect the taste of their eggs.
Chickens need a balanced diet to stay healthy, and a purely carnivorous diet would leave them deficient in important nutrients. High-quality chicken feed, supplemented with treats like meat, insects, and plants, will ensure they get all the vitamins and minerals they need.

Vegetarian-fed chickens are often raised in confinement without access to the outdoors
Chickens are omnivores and in their natural environment, they eat all kinds of outdoor goodies, including grasshoppers, mealworms, black soldier fly larvae, and other meat bits and insects. This is often at odds with the desire of some consumers to buy eggs from chickens fed a vegetarian diet.
Some companies advertise that their hens get vegetarian diets, but chickens are omnivores, and their nutrition depends on proteins often unavailable in vegetarian sources. Chickens on an unsupplemented vegetarian diet typically fall short of an essential protein-based amino acid known as methionine, and without it, they fall ill. Worse, the birds will also turn on each other, pecking at each other in search of nutrients, and these incidents can escalate. To get around this, many products will feed their chickens a ration of soybeans and corn that is supplemented with synthetic methionine.
Some companies, like Perdue, have opted to feed their chickens a 100% vegetarian diet, with no animal by-products, and care for them in a clean, safe environment. They get protein from soybeans, and fats from vegetable oils – mixed with corn and other grains for energy, along with vitamins, minerals and probiotics that help keep them healthy without antibiotics.
However, vegetarian-fed chickens are almost always raised in confinement without access to the outdoors. This is because chickens that are allowed to free-range will naturally eat bugs and other meat bits.

Vegetarian-fed chickens can suffer from amino acid deficiencies, particularly methionine
Chickens are natural omnivores. While it is possible to create a chicken feed that is made solely from plant materials, it is claimed that chickens on a vegetarian diet can fall short of an essential amino acid found in a protein named methionine. Without it, they can become extremely sick and even exhibit aggressive behaviour towards each other.
Methionine-deficient diets produce an imbalance of nutrients, which can affect the digestibility of essential amino acids by altering the gene expression of amino acid transporters. Studies have shown that growing birds fed a methionine-deficient diet had reduced growth and worse feed efficiency compared to those on a balanced diet.
To compensate for the lack of methionine in a vegetarian diet, some chicken feed products supplement their feed with synthetic methionine. These chickens are then fed a ration of soybeans and corn, which provides them with the necessary protein. However, the levels of artificial methionine are often so low that chickens still experience health consequences and even early death.
Some people who keep chickens may be concerned about the inclusion of animal by-products in their feed, especially if they are vegetarians themselves. Animal by-products can include low-cost, rendered bits leftover from processing, such as fats skimmed from processing plant wastewater or recycled from used restaurant grease. However, it is important to note that chickens in their natural environment will eat all kinds of outdoor goodies, including grasshoppers, mealworms, and black soldier fly larvae.
Overall, while it is possible to feed chickens a vegetarian diet, it is important to be aware of the potential amino acid deficiencies, particularly methionine, that can occur and take steps to supplement their diet appropriately.

Chickens fed a vegetarian diet are less likely to be consuming slaughterhouse waste
Chickens are not vegetarians by nature. They are omnivores, meaning they have the ability and desire to consume and digest a wide variety of foods from both plant and animal species. Their pre-domesticated ancestors, the Red and Green Jungle Fowl, native to South Asia, had a diet consisting of a wide variety of materials, including fruits, seeds, leaves, insects, worms, small mammals, and even snakes.
However, in modern times, there has been a push for vegetarian-fed chickens, with some companies advertising their poultry products as coming from chickens fed a 100% vegetarian diet. This marketing tactic appeals to consumers who believe that purchasing meat from vegetarian-fed chickens is more ethical and natural.
While the intention behind this push may be good, feeding chickens a vegetarian diet does have its drawbacks. Chickens fed a vegetarian diet are less likely to be consuming slaughterhouse waste, which was a common practice in the past. Historically, farmers would feed their chickens a mixture of grain and slaughterhouse scraps, including leftover trimmings and rendering scraps from muscle, tendons, fat, skin, and bone dust from butchering beef and pork. This practice provided chickens with essential amino acids, specifically methionine, which is abundant in meat.
Today, to compensate for the lack of animal-based nutrients in a vegetarian diet, chickens are often given supplements like synthetic methionine or limestone, which is high in calcium. This has led to an overreliance on a small number of global suppliers for these critical ingredients. Additionally, some companies that advertise their chickens as "vegetarian-fed" actually supplement their diets with insects or fishmeal, which provides the necessary animal-based protein.
In conclusion, while chickens fed a vegetarian diet are less likely to be consuming slaughterhouse waste, this practice may not be ideal for the chickens' health and wellbeing. A well-rounded, wholesome diet for chickens includes both plant matter and animal-based proteins and fats, which they can obtain from their natural foraging habits if allowed access to the outdoors.

Vegetarian-fed chickens are advertised as being better for consumers, but not necessarily for the chickens
Vegetarian-fed chickens are a growing trend, with many consumers believing that eggs from these chickens are healthier, fresher, and cleaner-tasting. The demand for vegetarian-fed chickens is especially high among vegetarians who eat eggs, as they want to ensure that the eggs they consume are not laid by hens fed animal by-products.
However, chickens are natural omnivores, and their diet in the wild includes bugs, grass, and small animals. As a result, forcing chickens into a vegetarian diet can be detrimental to their health. Chickens on a vegetarian diet typically suffer from a deficiency in methionine, an essential protein-based amino acid. This deficiency can make them ill and cause aggressive behaviour, leading to incidents of cannibalism among the flock. To compensate for this deficiency, farmers may supplement the diet with synthetic methionine, but there are limits on how much of this non-organic substance can be used, and some argue that these restrictions harm the chickens.
To ensure that chickens do not consume any meat, they are often raised in confinement without access to the outdoors. This practice has been criticised as inhumane, denying chickens their natural instincts and the space they need to thrive.
While the advertising of vegetarian-fed chickens may appeal to consumers, especially vegetarians, it is important to consider the potential negative impact on the chickens' health and welfare.
