“True human goodness, in all its purity and freedom, can come to the fore only when its recipient has no power. Mankind's true moral test, its fundamental test (which lies deeply buried from view) consists of its attitude toward those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it.”
— Milan Kundera in The Unbearable Lightness of Being

Chicken-human behavioral similarities

The Startling Intelligence of the Common Chicken: Chickens are smart, and they understand their world, which raises troubling questions about how they are treated on factory farms
Excerpt: “ … [Chickens empathize] with individuals that are in danger.”
Comment: Or sick: On beautiful days, when my chickens would otherwise be eager to go out hunting for bugs, they'd instead sit inside next to one dying of cancer, also shunning food just to be with her hour after hour.

Think chicken: Think intelligent, caring and complex: Review looks at studies on chicken intelligence, social development and emotions
Excerpt: “Chickens are not as clueless or 'bird-brained' as people believe them to be. They have distinct personalities and can outmaneuver one another. They know their place in the pecking order, and can reason by deduction, which is an ability that humans develop by the age of seven. Chicken intelligence is therefore unnecessarily underestimated and overshadowed by other avian groups.”

Can some birds be just as smart as apes?

Chickens and humans possess many similarities in behavior and social hierarchy. Although chickens are often disparaged as being dumb animals, observant chicken owners know otherwise.

Like many people, before I got chickens, I assumed they were stupid animals devoid of personalities—basically egg-laying machines. However, after I brought them home, I quickly fell in love with them; I call them my “kids” or my “babies.” Now it's not about the eggs, but a chance to give a wonderful life to animals that can indeed enjoy life, as I learned. Chickens exhibit surprising intelligence and marked individuality. I've noticed many parallels between chicken and human behavior. Here are some of them:

People obviously love tasty food. So do chickens. When my chickens were young, they would squeal with delight when given one of their treats, such as currants, but also simple pleasures such as fresh water, which they would instantly devour with zest. As adults, they slowly peck at crumble, their primary food they eat only if nothing else is available, but they peck like animated jackhammers when given something yummy, such as raisins, watermelon, other melons, black olives, flax, green and especially purple cabbage, oatmeal, corn on the cob (a favorite!), sweet potatoes, cheese, scrambled eggs, and egg shells. They also love blackberries, but what I can pick in 15 minutes, they can eat in seconds. But just as humans become accustomed to pleasures and eventually derive less thrill from them, so do chickens. The breakfast I served this morning once would have elicited prolonged Happy Baby sounds but instead evoked bored disappointment and rejection analogous to turning up one's nose—what I call turning up their beaks. Also as with humans, the best antidote is to withdraw the pleasure and later reintroduce it.

Just as humans often fiercely compete for the most desirable possessions and partners, chickens compete for the tastiest food but not the commonplace stuff. While chickens can be competitive (as evidenced by eating yummy food as rapidly as possible to get as much as possible when other chickens are near), they can also be remarkably altruistic by emitting a sound to call other chickens, essentially saying, “I found something really tasty. Come and get it!”

Taste matters to chickens, but so does color. They prefer brightly colored food: red, blue, purple, yellow, and green. Picking foods with such natural colors is a smart way to obtain powerful antioxidants and essential nutrients. A ScienceDaily article, Colorful Plates Boost a Picky Eater's Appetite, said:

“Parents of picky eaters can encourage their children to eat more nutritionally diverse diets by introducing more color to their meals, according to a new Cornell University study. The study finds that colorful food fare is more appealing to children than adults.”

It's more appealing to chickens, too. :-)

Chickens love sugar. I recently gave my chickens oatmeal as a treat, placing it on a paper plate I'd used to eat gluten-free pumpkin bread with a light sugar glaze, some of which stuck to the plate and dried. Chickens like oatmeal, but enjoy sugar even more; they seem to have radar for it. It took precisely one peck for the chicken to find the small nuggets of dried frosting adhering to the plate. She used that as a handle to pick the plate up, which dumped the oatmeal on the ground. She then walked around for a few minutes holding the now-vertical plate in her beak, as other chickens pecked at other sugar blobs on the plate. The amount of sugar totaled less than 1% of the oatmeal, which the chickens ignored even though it was in a surprisingly neat pile. Sugar is more yummy.

Chickens want what others have. Put a plate full of treats on the ground and the first chicken to reach it will often run off holding a treat in her beak while other hens run after her, trying to steal the food away, evidently thinking her treat is more valuable than the ones remaining on the plate: treats they could have all to themselves instead of chasing after a bird determined to keep what she has. Similarly, humans sometimes assume that what others have (such as a particular partner) is automatically more desirable than what they have. Cognizant of this, some women increase their appeal by inviting a male friend to accompany them.

Chickens are inquisitive and love to explore, even things that obviously contain no sources of food. For example, my chickens often hop onto my tractor or bulldozer while I work on their engines. They'll peer inside, tilt their heads, look at me, and keep doing that.

Chickens get bored eating and doing the same things. They crave variety. If they are free, they frequently move from one spot to another, such as hunting for bugs in the forest leaves, then in the grass, then in another grassy spot, and another. Then it might be time for a dust bath, or just basking in the sun, followed by more hunting in various places. Then they might hang out around me to see what I am doing or beg for treats, after which they might spend an hour or two in one of their favorite shady hang-out spots. Then more hunting for bugs as they slowly meander back to their coop in the evening. Once there, it's always time for a bedtime snack.

Unfortunately, most chickens in developed countries are either slaughtered for meat when they are very young or confined in cages so crowded they're like sardines in a can. Once chickens are given a taste of freedom, they—like humans—relish it, valuing it even more than safety and security.

As proof of that, consider my chickens, who know they are safe in the large pen attached to their coop that gives them considerably more square feet per bird than average. While in that pen, I've never seen them display the defensive behaviors they exhibit when they are free and exposed, such as frequently looking in the sky for predatory birds or listening and responding to potentially threatening sounds. In that pen, they have everything they need: water, food, and even a variety of tasty treats they attack like starved teenagers gobbling a pizza.

While chickens crave freedom once they experience it, chickens who don't know what it is like to be free are more tolerant of restrictions. My chickens rarely return to the safety of their pen or coop during the day unless they are terrified by a predator. Even when they are on high alert and are constantly looking and listening for sounds that signal danger, they would rather be free and in peril than safe and secure. Thus, chickens want freedom even if they have everything they need in captivity. Too bad most Americans don't.

My chickens are content in their pen only for a few minutes in the morning after exiting their coop. After a quick breakfast, they are eager to be freed so they can hunt for worms and assorted bugs on land that is strangely devoid of them. It doesn't matter. They often prefer hunting and striking out to eating crumble (their usual “chicken food” fare) or even platefuls of treats I know they love. If I don't free them to run around, they quickly get bored. Some will mope around as if they are depressed while the more vociferous ones make pitiful loud squawking sounds analogous to human crying, voicing their displeasure at being deprived of an accustomed pleasure.

Seconds after letting them loose, they make happy chicken sounds, analogous to happy baby sounds, and they are infused with energy as they scratch the ground and overturn leaves looking for something to eat. Hours of that activity yields less food than what they can wolf down in less than a minute while eating treats they clearly prefer to crumble. Thus, hunting for food is often more fun than eating it. Even when chickens have an endless supply of tasty food, they usually prefer to hunt for bugs, even if the search is fruitless.

The dumbest and smartest cause most of the problems.

The chicken at the top of the pecking order often isn't the smartest, just the most willing to ruthlessly attack others to put them in their place.

Those at the top of the pecking order get more resources (food in the case of chickens) that enables them to become larger and more powerful: the rich get richer.

Those at the top of the pecking order don't give a hoot about fairness or helping others even when there are more than enough resources for everyone. They hog resources and intimidate or attack others to deter them from getting their fair share.

Those at or near the bottom of the pecking order behave in a submissive manner and may appear stupid or unfriendly, but can come out of their shells and blossom if given a chance. This marked change in chickens can also happen in people, but few know how to catalyze such positive metamorphoses. Instead, people often enjoy bashing the imperfections and mistakes of others instead of helping them improve.

Interesting observation: After the alpha-chicken (the one at the top of the pecking order) died, the remaining chickens didn't fight to see who'd be #1; they all just got along in peace and harmony. With humans, the presumption is that we need leaders and government and would be lost without them. I have my doubts about that, and I wonder if they do us more harm than good. If the government collapsed, as it likely will, would you rob your neighbor? I wouldn't. If anything, I'd reach out more to others to see if they needed any help. Government enacts countless laws to force us to do what most of us would do on our own without any arm-twisting: treat others fairly and with respect, as we'd wish to be treated (the Golden Rule).

The most basic principle of civilization is cooperation. If chickens, often disparaged as bird-brains, can figure out how to share a plate of tasty food they all eagerly want, why can't humans cooperate and get along with one another without government? We could.

Cooperation is adaptive: that is, it enhances your probability of survival. If humans didn't innately realize the adaptive benefit of cooperation, they never would have survived long enough to form governments—governments of kings and dictators motivated not by the Golden Rule, but by usurping the lion's share for the rulers and their supporters. It is still the same way today, even in the United States, with politicians stealing our money to reward their special interests.

Arguably our most precious asset—our money—is controlled by the Federal Reserve System, not a part of the federal government as many people think, but a private corporation that acts in cahoots with our leaders to steal our money by diluting its value. They do that by literally creating money out of thin air. If you create money, you're a counterfeiter. That's a crime because it dilutes the value of existing money. The laws of economics are as immutable as the laws of physics; money cannot be created out of thin air and put into circulation without it lessening the value of existing money, such as the money in your bank account and 401(k) plan.

“It is well enough that people of the nation do not understand our banking and monetary system, for if they did, I believe there would be a revolution before tomorrow morning.”
Henry Ford

Chickens have favorite buddies to hang out with, but their friendships may change over time. Relevant research: Birds choose their neighbors based on personality.

Chickens have favorite hang-out spots, which may also change in time.

Chickens love to be comfortable. I discussed this with a chicken-loving expert who said that nature gives chickens and other animals the insulation and metabolism they need to stay warm in winter. Wrong; nature enables them to survive (usually), not be comfortable! Here's proof: My chickens hate to be in their coop, except during the winter when it is heated. At other times, as soon as I open the door to let them out in the morning, they almost climb over one another to exit first. However, when I open their door during winter, they will often whimper and refuse to come out during a 40° day even when tempted by a treat, such as scrambled eggs, they would otherwise rush to get (they're often so eager to get it they'll hop up before I have a chance to set the plates on the ground).

Wild animals are often miserable during winter, which is why I make shelters for them and created a site about that topic. One of the shelters I made is about 200 feet long and home to lots of animals who clearly prefer the coziness of this Hilton for Critters that blocks wind and provides insulation.

Chickens are more likely to behave if they had their fill of fun that day. If they had only a couple hours of freedom that day, it is often difficult to coax them back into their pen and then coop. If they didn't obtain their MDR (minimum daily requirement) of fun, they will stay out past the time when darkness—and its associated dangers—otherwise compels them to head in for the night. However, if they were free most of the day, getting them into the pen and coop is much easier.

As much as chickens love eating, foraging for food, and dust baths, I saw evidence of the depth of chicken emotion when two of the three birds in the flock spent days sitting with a dying one who couldn't walk.

Chickens have a long-term memory of danger, which I discussed in another article after showing a picture of Mark Zuckerberg holding a dead chicken he likely killed. “Birds, reptiles and mammals are all descended from a common ancestor,” so by slitting the throats of chickens, Zuckerberg is slitting the throats of relatives—very distant ones, of course, but still relatives.

One more thing: I've learned much more from chickens than they've learned from me. That valuable lesson should be extrapolated by educators who think imparting knowledge is a one-way street with students the inevitable receivers and teachers or professors always the transmitters. That attitude spills over to others, such as LinkedIn influencers who never engage with readers, as if they always know more even though some of them possess amateurish levels of knowledge.

    Comment: Human mistreatment of countless animals is simply unconscionable. Part of this stems from ignorance, part from callous indifference, and part from religious beliefs that God put all these animals on Earth for us to slaughter any frigging way we see fit, even if it inflicts terrible pain. Yup, God cares more about us eating more than we should and inflating our fat cells more than He cares about us doing the right thing. This is clearly an example of might makes right: killing in inhumane ways because we can, and because we can get away with it. This is a moral abomination, not something to tolerate. If you believe in God, do you really believe He gave many animals the ability to experience emotions and pain that permits people to intensify their misery? Isn't that needlessly cruel? What's the point in that? Some kind of sick joke? If you believe in religion, and you believe that God is good, you may wish to consider the possibility that He looks favorably upon people who treat animals with as much kindness and respect as possible.

    Comment: People are also more likely to say or do things they really don't mean, or later regret, when they are exhausted, such as some of my blog postings during my years of extreme sleep deprivation. Toward the end of a few long night shifts in the ER (especially if I began the 12 – 15-hour shift exhausted), I said some things I ordinarily wouldn't say. Nothing shocking, just a bit too much relaxation of the normal self-censoring most of us (except Vice President Biden) routinely do. I give him a pass because of his prior brain surgery, but dog-tired people deserve a bit of understanding that what comes out when they're drained is not them. If everyone were judged by their worst behavior, we'd all be in trouble. Or prison.

Excerpt: “In a brief video before the interview, Soleim described her chickens as her "babies" …”
Comment: Chickens are considerably more intelligent and emotionally expressive than most people suspect (or admit), as I proved beyond a reasonable doubt in this article including hundreds of references indicating that many animals are surprisingly intelligent (in some aspects equaling or surpassing human intelligence) and equally capable of being depressed or elated. Acknowledging this reality raises thorny questions about the morality of what we do to various animals so most people, conveniently, comfort themselves by thinking that humans are vastly superior and other animals are so inferior they can be treated like animals — or dirt. Kudos to Tiara Soleim.

The meat paradox: “When we eat [meat], we do it in denial. … by referring to what we eat as "beef" instead of "cow", we have created a distance between our food and an animal with abilities to think and feel. Philosophers and animal rights activists have long claimed that we avoid thinking about the animal we eat, and that this reduces the feeling of unease.”

The views expressed on this page may or may not reflect my current opinions, nor do they necessarily represent my past ones. After reading a slice of what I wrote in my various websites and books, you may conclude that I am a liberal Democrat or a conservative Republican. Wrong; there is a better alternative. Just as the primary benefit from debate classes results when students present and defend opinions contrary to their own, I use a similar strategy as a creative writing tool to expand my brainpower—and yours. Mystified? Stay tuned for an explanation. PS: The wheels in your head are already turning a bit faster, aren't they?
