Chickens Are Smart and Have Feelings, Contrary to ‘Bird Brain’ Stereotypes

By Seth Millstein, Sentient Media

Many research over the years have proven that chickens are smart, intelligent and feeling creatures. Yet there may be nonetheless a widespread assumption that chickens are usually not good animals. This could also be as a result of how carefully we affiliate them with meals: in spite of everything, chicken is the most popular meat in the United States, with the common American consuming almost 100 kilos of hen yearly. Over 70 billion chickens are slaughtered worldwide yearly, which is over 20 instances the variety of pigs, sheep and cows mixed.

We have each motive to consider chickens are cognizant of their very own struggling. They are able to reasoning, empathizing, deducing and deceiving. They play with one another, sense when their young are in peril, acknowledge their house owners and warn one another of close by threats. Chickens may even carry out mathematical calculations, and are able to studying some ideas — corresponding to object permanence and basic structural engineering — sooner than people.

According to the Sentience Institute, 99.9 % of chickens raised for meat (often called “broiler chickens”) within the U.S. reside out their lives in punishing manufacturing facility farms. The abundance of evidence showing chicken intelligence has led many animal ethicists and advocates to query their confinement.

So, what can we find out about the minds of chickens? How good are these birds, and what would possibly they be pondering and feeling?

What Makes Chickens Smart?

First, it’s value asking what precisely it means for a non-human animal to be “smart.” The idea of intelligence itself was invented by people, for people; once we name a person “smart,” we imply that they’ve a mix of information and cognitive skills that allow them to thrive as people. To decide whether or not chickens are smart, then, we should always ask: Do they’ve the requisite abilities and skills to outlive and thrive as chickens?

The reply to that query is a powerful sure. Chickens are prey creatures with no pure defenses, and but they’ve been in a position to survive and thrive for 1000’s of years, thanks in no small half to their intelligence. Let’s check out how.

Chickens Have A Lot To Say

Chickens are highly communicative: Using over 20 distinct vocalizations, they sign to 1 one other “with remarkable precision about critical events in their world,” in line with Dr. Chris Evans of Macquarie University. Chickens greet one another, specific frustration, sign the presence of meals, and announce after they’ve simply laid an egg. They have totally different warning calls that they use when hazard is approaching — one for air-based predators, one other for ground-based predators — and a separate warning when a human tries to steal their eggs. Remarkably, some chickens even “name” their owners, writes Melissa Caughey in her ebook “How To Speak Chicken,” and use distinct cluck patterns to greet them.

Chickens Have Self-Control

In a 2005 study, chickens had been offered with a button that, when pressed, gave them meals. If they waited solely a few seconds earlier than pushing the button, they obtained a small quantity of meals, but when they waited a further 20 seconds, they obtained a a lot bigger bounty. Researchers discovered that 90 % of the time, the chickens chose to wait for the larger prize. This demonstrated that the birds possess self-control and, by extension, the power to challenge into the close to future.

“An animal that can anticipate an event might benefit from cues to aid prediction, but may also be capable of expectations rendering it vulnerable to thwarting, frustration and pre-emptive anxiety,” famous Dr. Siobhan Abeyesinghe, writer of the examine. “The types of mental ability the animal possesses, therefore, dictate how they should best be managed and what we might be able to do to minimize psychological stress” in manufacturing facility farms.

Chickens Can Perform Basic Arithmetic

Chickens have a strikingly sophisticated awareness of numbers and math: A 2017 examine confirmed that they’ll add, subtract, evaluate knowledge units and depend from left to proper, whereas a 2009 examine demonstrated that newborn chicks are able to follow and win easy shell video games.

“Chickens have the capacity to master skills and develop abilities that a human child can take months and years to accomplish,” writes Dr. Christine Nicol in her examine, “The Intelligent Hen.”

In one experiment, objects had been placed behind one in every of two obstructions after which shuffled forwards and backwards. The chicks who noticed the shuffling had been in a position to hold monitor of which objects had been the place, and had been persistently in a position to choose the obstruction with probably the most objects behind it. In doing so, these chicks demonstrated not simply mathematical skills however object permanence, or the power to grasp that an object nonetheless exists even when it’s been obscured. Humans don’t learn object permanence till they’re two years old; these chicks, in contrast, had been in a position to grasp the idea simply 5 days after they hatched.

Chickens Protect and Empathize With Each Other

Like many different species, chickens are extraordinarily protecting of their young. A 2011 examine discovered that mother hens stop preening and improve their misery vocalizations when their chicks seem visibly upset; this, the researchers defined, proves that “adult female birds possess at least one of the essential underpinning attributes of empathy.”

A 2013 examine elaborated on this analysis and located that, relating to the security of their chicks, hens are much more observant. In that examine, mother hens behaved protectively not simply after they witnessed their chicks in misery, but in addition after they acknowledged that their chicks had been in an surroundings that the hen, based mostly on her current data of threats and predators, acknowledged as probably harmful.

Chickens Can Be Manipulative

Chickens are able to many constructive social behaviors, however they may also be mischievous tricksters. Roosters will sometimes signal that food is near even when it isn’t with a view to entice hens. Eventually, the hens sensible up, and cease responding to these calls.

“These kinds of social strategies—deception and counter-strategies—are strikingly similar to the same kinds of complex behaviors identified in mammals, including primates,” writes Dr. Marino, writer of an article on hen intelligence within the journal Animal Cognition.

Chickens Can Recognize Their Owners

Chickens can recognize up to 100 faces, they usually associate the faces they remember with constructive or unfavourable experiences, in line with Marino’s examine. They additionally show love and affection for the people who take care of them, and reply to totally different people in a different way based mostly on how these folks have handled them.

Chickens Are Individuals

Anybody with a flock of their yard can let you know that chickens have individual personalities. Some are pleasant, feisty and affectionate; others are cantankerous, lazy and stand-offish. It all will depend on the fowl.

“There is an abundance of anecdotal evidence for individual personalities in chickens from sanctuaries, small farmers, and people who keep backyard chickens,” Dr. Marino writes. “[They] show notable abilities to recognize individuals in their social group, as well as the ability to keep track of the group’s social hierarchy and the individuals within it…Not only do chickens recognize who is and is not a member of their social group, but they differentiate individuals within their own group.”

It’s with these skills that chickens are in a position to create and keep the pecking order, which is essential to their survival as prey animals.

Chickens Can Feel Pain

Let there be no misunderstanding: Like people and different animals, chickens can and do feel pain.

“[Pain receptors] have been identified and physiologically characterized in many different parts of the body of the chicken including the beak, mouth, nose, joint capsule, and scaly skin,” in line with a examine printed in Applied Animal Behavior Science. “Stimulation of these [receptors] produces cardiovascular and behavioral changes consistent with those seen in mammals and are indicative of pain perception.”

Unfortunately, many widespread practices in poultry farming are liable to trigger the chickens excessive ache. For occasion, slicing the beaks off of new child chicks previous to slaughter —  widespread observe for broiler chickens — is acutely painful to the birds. Meanwhile, long run illnesses like orthopedic illness and damaged bones are widespread in broiler chickens; this may increasingly trigger them continual ache, which may final for weeks or months.

Broiler chickens are bred to develop massive in a short time — they’re slaughtered at roughly 45 days old — and analysis reveals that they endure from the bodily results of this unnaturally paced development. A recent examine from the Global Animal Partnership concluded that chickens raised for faster growth “had lower activity levels, poorer indicators of mobility, poorer foot and hock health, higher biochemical markers of muscle damage, higher rates of muscle myopathies, and potentially inadequate organ development.”

Are Chickens Similar to Companion Animals?

In some ways, chickens are very similar to the animals we usually consider as family companions. Like dogs and cats, they’re distinctive people with totally different personalities, and are sometimes inquisitive, playful and affectionate.

The normal public is steadily coming to see the birds on this gentle. According to the Los Angeles Times, domestic chicken ownership is “one of the fastest-growing hobbies in the US,” with multiple %  of American households elevating chickens as of 2017.

However, chickens even have totally different wants than the animals extra generally considered “pets.” Because of this, house owners may not at all times be as geared up as they suppose they’re to maintain them humanely.

How Can I Tell If My Chickens Are Happy?

The Farm Animal Welfare Council has established welfare requirements for farmed animals, often called the “Five Freedoms.” They are as follows:

• Freedom from Hunger and Thirst
• Freedom from Discomfort
• Freedom from Pain, Injury, or Disease
• Freedom to Express Normal Behavior
• Freedom from Fear and Distress

This would appear to be a comparatively low bar, and it’s typically a simple one to fulfill for folks elevating a small flock of their backyards. But in manufacturing facility farms, it’s a unique story. Undercover investigations have revealed that even on farms held to “high” animal welfare standards, chickens  endure. Many don’t even survive till slaughter.

“There are many ways of telling if a chicken is suffering,” animal welfare researcher Dr. Mary Baxter writes in The Conversation. “But to create truly positive environments for farmed broiler chickens, researchers must find ways of measuring their contentedness.”

So, what are indicators of happiness in chickens? One is the extent to which they play with each other.

In the Nineteen Fifties and ‘60s, researchers noticed play-like conduct in chickens, which they described as “frolicking,” “sparring” and “food running.” Scientists later gave these behaviors totally different names, referring to them as “aggression” or “running-with-flapping.” This rebrand, Baxter writes, was “probably because of the general reluctance among scientists to attribute emotion or awareness to birds.”

But no matter you name that conduct, it ”match[s] inside well-established definitions of animal play,” Baxter says.

We don’t must look solely to trade pointers to grasp the conduct of chickens. Those who’ve interacted with them, be it at an animal sanctuary or in their very own yard, will let you know that chickens often purr when happy.

The Bottom Line

The proof that chickens are clever and able to feeling ache — and that they endure in manufacturing facility farms — is overwhelming. But as a result of we farm and kill chickens by the billions yearly, there should still be a disconnect in our potential to see these animals as sentient. Marino believes that to grasp chickens’ mind, we have to begin finding out them from a unique viewpoint. “Most of the work that’s done on chickens, fish, and cows tends to involve trying to figure out how to make them lay more eggs or grow faster or not peck each other. It’s all very applied, and it misses the whole point,” Marino told Mental Floss. “These are animals who have an evolutionary and adaptive history, just like a chimpanzee or a dog or a human being. They’re animals. And at the very least, we need to approach them as animals in their own right.”
