Chickens and cows are two very different animals, and the differences between them are quite stark. A chicken is a domestic fowl, while a cow is a female domesticated ox or other bovine, especially an adult that has had a calf. Cows are significantly larger than chickens, and their brain size is also much bigger. This has led to debates about whether eating chicken is less ethical than eating beef, as a single cow provides hundreds of meals compared to a chicken. In addition, the meat of these animals has historically been referred to using different terminology, with beef and pork being derived from French words, while chicken has always been called by its English name.

What You'll Learn
Brain size
The brain size of a chicken is about 3 grams, while a cow's brain weighs between 450 and 500 grams, or 480 grams according to another source. This means that a cow's brain is about 150 times larger than that of a chicken.
It is worth noting that brain size is not the only factor that determines cognitive abilities. Neuroscientist Suzana Herculano-Houzel argues that neuron count may be a better indicator of cognitive abilities than brain size. She estimates that a cow's brain contains about 3 billion neurons, while the Red Junglefowl (a wild relative of domesticated chickens) has around 221 million neurons.
In terms of relative brain size, domestic cattle have brains that are about 25% smaller than those of their wild ancestors. This reduction in brain size is attributed to the process of domestication and the amount of human contact the animals receive. Dairy cows, for example, have the smallest brains among cattle breeds due to their gentle nature and frequent interaction with humans.
On the other hand, the Lidia breed of cattle, which is known for its aggressive behaviour, has the largest brain size among European domestic breeds. This suggests that brain size may be linked to certain behaviours or characteristics.
Overall, while there is a significant difference in brain size between cows and chickens, other factors such as neuron count and brain structure also play a role in cognitive abilities and behaviour.

Meat names
The meat of a cow is called beef, and the meat of a pig is called pork. In contrast, chicken meat is called chicken. This difference in naming conventions can be attributed to the social and historical contexts surrounding the consumption of these meats.
During the Middle Ages, the social hierarchy in England was divided between the French-speaking nobles and the Anglo-Saxon or Old English-speaking peasants. The nobles, being the dominant consumers of meat, would refer to cow meat as "boeuf" (which evolved into the modern English "beef"), pig meat as "porc" (which became "pork"), and chicken as "poulet" (translated as "poultry"). However, the peasants, who had closer contact with the animals and primarily consumed cheaper meats like chicken, continued to use the English terms "cow", "pig", and "chicken".
Another factor influencing the naming conventions is the availability and affordability of chicken compared to other meats. Chicken was more readily available to commoners and was considered cheaper than other meats during certain periods. As a result, chicken meat retained its English name, while the names of other meats were influenced by the French language and norms of the upper classes.
Today, the names "beef" and "pork" are used to create a degree of separation between the animal and the meat, allowing consumers to distance themselves from the idea of eating a particular animal. This disassociation is less prevalent with chicken, as it is lower on the "evolutionary ladder" and is considered less exotic.
In summary, the names of meats like beef and pork are derived from the French language and were adopted due to the influence of the upper classes in medieval England. In contrast, chicken meat retained its English name, reflecting the language and consumption patterns of the lower classes during that historical period.

Social status
Cows and chickens have long been important domesticated animals, with cows providing meat, milk, and labour, and chickens providing meat and eggs. In the Middle Ages, cows and chickens had different social statuses, with cows being consumed by the wealthy and powerful, and chickens being eaten by the lower classes. Chickens were also kept by peasants for their eggs.
Cows are social animals that live in herds. They are able to form social bonds and relationships, with the first social bond formed between a cow and her calf. Social relationships between cows may change with age and play a role in determining an individual's position within a group's overall social structure. Cows engage in mock fights to test each other's strength in a non-aggressive way, and they can also be trained to recognise individuals using olfaction. Licking is primarily performed by subordinates and received by dominant animals. Mounting is a playful behaviour shown by calves of both sexes and sometimes by cows in oestrus, but it is not related to dominance.
The social status of cows within a herd is determined by a dominance hierarchy, which is influenced by age and sex, with older animals usually dominant over young ones and males dominant over females. Young bulls gain superior dominance status over adult cows when they reach about two years of age. Individual cows also display different personality traits, such as fearfulness and sociability, which can influence their social status.
Chickens are also social animals with complex vocalisations and behaviours. They live in flocks and raise their young communally. Chickens have individual personalities and are capable of showing affection. They are kept as pets by many people, especially in urban and suburban areas.
Within a flock, chickens establish a pecking order, with dominant individuals taking priority for access to food and nest sites. Male chickens use their claws in conflicts and will crow loudly as a territorial signal to other males. Hens, on the other hand, cluck loudly after laying an egg and to call their chicks.

Size
One of the most notable differences between cows and chickens is their size. Cows are significantly larger than chickens, with a brain size of 480 grams compared to a chicken's brain size of 3 grams. This difference in brain size has led to discussions about the moral significance of the two animals, with some arguing that a cow may be hundreds of times more morally significant than a chicken due to its larger size.
In terms of physical dimensions, cows are typically much taller and heavier than chickens. Cows can weigh several hundred kilograms, while chickens usually weigh only a few kilograms. This size difference is partly due to the different life stages of the two animals, as cows are typically considered adults after they have had a calf, while chickens are often referred to as young or spring chickens.
The size difference between cows and chickens has practical implications as well. For example, in the context of farming and food production, a single chicken may be considered a large meal, while a cow can provide hundreds of meals. This makes chicken a more affordable option for many people, and it is often consumed by lower-class families. In contrast, beef is generally considered a more expensive cut of meat and is more likely to be consumed by the upper classes.
The size difference between cows and chickens also has cultural implications. For example, in the English language, there are different terms for the meat of a cow ("beef") and the meat of a chicken ("poultry"). This distinction is said to originate from the Norman invasion of England, where the French-speaking nobles ate the more expensive meat of cows, while the English-speaking peasants consumed the more affordable meat of chickens, leading to the persistence of different terminology for each animal and their respective meats.
Overall, the size difference between cows and chickens is significant and has implications for their moral, practical, and cultural significance. Cows, with their larger size, are considered more morally significant and provide more meals, while chickens, being smaller and more affordable, have played a different role in human society and language.

Behaviour
Chickens and cows are both social animals, but they exhibit different social behaviours due to their distinct natural habitats and physical characteristics. Chickens live in flocks and have a pecking order within their groups, which they establish through various vocalizations and body language. They are known for their high reproductive rate, with hens laying eggs regularly throughout the year. On the other hand, cows form herds and also establish hierarchies within their groups. They are known to form strong bonds with their offspring, and their gestation period is longer, typically giving birth to a single calf.
Chickens are omnivores with a varied diet that includes grains, seeds, insects, and even small animals. They require a balanced diet to ensure proper growth and egg production. Cows, on the other hand, are herbivores and primarily eat grass and other plant materials. They have a complex digestive system that allows them to break down cellulose and extract nutrients from plants efficiently.
The social behaviour of chickens and cows also differs in terms of their interaction with humans. Chickens have been domesticated and are commonly raised for their meat and eggs, feathers, and manure. They are known to exhibit complex behaviours such as dust bathing and roosting. Cows, too, have been domesticated and are valued for their meat and milk, leather, and hides. While chickens have a shorter lifespan, some cow breeds can live up to 20 years.
Additionally, the size and physical characteristics of chickens and cows contribute to their distinct behaviours. Chickens are smaller and more agile, allowing them to move easily within their flocks. They have feathers and beaks, which are adapted for their omnivorous diet. Cows, in contrast, are larger and have hides and horns, which can be used for defence or establishing dominance within their herds.
While both chickens and cows exhibit a range of behaviours, it is important to note that individual personalities and environmental factors can also influence their actions. Additionally, as observed in the case of 'Lal the cow', individual cows may exhibit unusual behaviours, such as eating chickens, which may be motivated by mineral deficiencies or simply the opportunity to explore non-herbivorous dietary options.
