There may be a temptation to believe that aggressive roosters are mean, nasty, bad, evil, hostile, hate people or there was something someone did to cause the unwanted behavior, but none of that is true.

THE ROOSTER’S JOB

Roosters essentially have two jobs within a flock: To Protect and To Service. Flock survival depends on his ability to protect the hens and preserve his genes by mating. Just as there are different ways for humans to perform a given job, there are different ways for roosters to protect their flocks. Heredity, hormones, breed and individual disposition all play roles in determining which young males become aggressive adults.

THE ROOTS OF ROOSTER AGGRESSION

Historical Context
Historically, chickens were domesticated for sport. According to the authors of “The Chicken, A Natural History,” cockfighting originated in the Far East, dating as far back as 500 BCE in Ancient Greece and the Roman Empire. Cockfighting did not begin to fall out of favor in most societies until the 19th century. Certain breeds have been selectively bred for cockfighting and aggression over time, so it is reasonable to expect those breeds to retain the genetics for such aggression. Cornish, Malay, Modern Game and Shamos are classic examples of fighting breeds.

Prey Animals
Chickens are prey animals, which predisposes them to being suspicious of novel things and to view the unfamiliar, sudden or strange as a potential threat to their existence. A rooster is constantly on alert watching and listening for potential incursions into his territory. When he perceives a threat, it is his job to protect and defend them by any means necessary, including chasing threats away and sacrificing his life fighting a predator. Prey animals do not think like predators (humans, dogs, raccoons, coyotes, etc). Survival is the name of the chicken game and the head rooster is in charge of ensuring flock survival.

Chickens are prey animals and as such, are naturally wary of novel things and unfamiliar movements as potential threats to their lives. A roosters is constantly on alert for potential incursions into his territory.

Disposition
Every rooster is an individual with a unique personality, which may or may not meet any of the expectations for his breed. Any rooster of any breed can become aggressive just as any rooster of any breed can be a teddy bear.

Hormones
Aggression typically becomes apparent in cockerels when they reach puberty, generally any time after four months old. Sexual maturity ushers in the full load of testosterone, which is a behavior game changer for some. Sometimes male chicks exhibit chest-bumping, tough-guy behaviors, but more often than not it becomes obvious when a cockerel reaches sexual maturity and his hormones approach adult levels. A cockerel cannot be raised not to be an aggressive adult. All the handling, cuddling, talking, treat-offerings and spoiling in the world will not overcome heredity, hormones and individual disposition.

Is it possible to teach a rooster not to be aggressive?
No. You cannot prevent or cause aggression in a rooster. A cockerel cannot be raised in a way that ensures they will not become an aggressive adult regardless of any claim to the contrary. It may be possible for some people to work with particular roosters to come to an understanding with them, working within their social structure and rules, however, it is an extremely time-consuming process that every human coming into contact with that rooster would need to complete. So, while theoretically the primary caretaker of the flock might be able to convince an aggressive rooster that they are not a threat to the flock after much conditioning, other people, particularly children will still be at risk of being injured, frightened and worse.

Human Code of Conduct
It is never appropriate to be violent or aggressive towards roosters, nor is it acceptable to attempt to intimidate, humiliate or shame them. Never grab, push, swipe at, swat, chase, hobble, leash, kick or hold a rooster upside down in an attempt to establish dominance- doing so simply serves to reinforce his perception of certain humans as threats.

What to Do with an Aggressive Rooster
Backyard chicken keepers who do not want or cannot keep an aggressive or territorial rooster in their flock should try to find him a home, preferably on a large property where his protective nature will be an asset to a flock.

 I've got a major beef with the negative perceptions perpetrated by many rooster detractors. Until I began keeping chickens myself, I didn't realize that roosters are no noisier than barking dogs and while it's true that a rooster may crow at daybreak or in the middle of the night if disturbed, those noises are easily eliminated by either sound and light-proofing the coop or by bringing the rooster into another interior space (garage, basement).

We have several of our hens who are losing feathers all in the same places. We suspect our rooster has something to do with it but can’t be sure. In years past when we did not have a rooster we did not see our hens losing feathers on their backside and near their vent. Have you ever experienced a rooster being the culprit of such feather loss?

Hey Kathy. I miss seeing your posts since I stopped Facebook. I have noticed that they only time my boys get feisty is after they have seen me doing something they consider aggressive to the ladies. Such as trying to catch one, etc. I try to talk softly and be nice when I have to carry one of the ladies.

Cogburn was a bared rock rooster. He was very ill tempered. I wanted to get rid of him but I was afraid he was too mean and something bad would happen to him. He lived a long life in his yard. My grand kids wouldn’t go in the chicken yard and I carried a bamboo stick and wagged it in back of me because he would attack you when you turned your back. I got spurred more than once and still have one of the scars.

I had a wonderful tame rooster named Fredrick , he was my buddy I kept him outside the pen and the hens inside. He did farm chores etc with me, even knocked at my door for attention. I kept his Talons cut short. it never failed he would become aggressive when his talons were long. I read an article from a vet at one point that talked about hormones and talons. so I began to cut them, this worked beautifully!

I think the article should also discuss keeping such roosters as breeders. Does it make a difference? I’ve always culled attack roosters promptly for that reason.
