Most roosters are not aggressive towards people, but when one is, what is a backyard chicken keeper to do? Nobody wants to live in fear of being flogged, attacked, spurred or chased by one of their pet chickens and no one wants a child to be hurt or traumatized in their backyard. It can be confusing and upsetting to have a cockerel who was raised from a day old chick, handled often and spoiled, suddenly become aggressive. There may be a temptation to believe that human-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.

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.

Excellent, informative article about a topic that doesn’t get covered very much! I’ve had my fair share of personal experience with aggressive roosters. Something I believe that many novice chicken owners don’t realize is that, while we can make some few generalizations for a breed’s expected temperament, every bird is still its own individual and we have to be prepared for exceptions. Although most of my Silkies have lived up to the typical gentle, friendly nature so often raved about, even one of my cockerels in particular turned out to be quite the feisty little snot. It was such a… Read more »
I have a Polish roo that I have had since he was just a few days old. My husband was very active in raising him and the 3 hens that were bought at the same time. My roo, Joe, is 1.5years old now and only allows me near him or his hens. He is very aggressive toward everyone even my husband. But toward me he has got to be the most affectionate chicken I’ve ever had. He literally runs to me and puts his head in my coat or shirt and cuddles. He likes to drape his head and neck… Read more »
I had a barred Plymouth rock that I was absolutely petrified of….now a few years later I have my newest rooster…only 4 months old blue orpington….time will soon tell how he will be!
As of right now I have 4 roosters at the age of 3-4 months old. We only want to keep one rooster for our flock of hens and was wondering how do you tell on what ones to get rid of?
This is a great one!!!!
