Chicken Bullying Sick Chicken: Reasons, Signs, and Solution

Are you worrying about a chicken bullying sick ones in your flock? I’ve repeatedly seen this worrying chicken behavior as a professional chicken farmer. 

Chickens bullying sick chickens is a thing to worry about because if it’s not treated, it may lead to the death of the weak chicken. 

It is a complicated issue in chicken flocks, influenced by pecking order, stress, and sickness.

Chicken bullying is similar to human bullying. It occurs when one or more chickens repeatedly peck on or bully another chicken, often causing severe injury or death. 

Poultry raisers like me must understand this behavior, its origins, and possible treatments to protect the flock.

Understanding Chicken Behavior

Chickens live in flocks organized by a sophisticated social hierarchy called the “pecking order.” This hierarchy describes their social system, determining each chicken’s status in the flock. 

It determines their eating order and nighttime roosting place. The name “pecking order” is linked to how chickens develop and maintain this social position, where a peck can mean much more.

Bullying doesn’t always include bird pecking. Instead, chickens naturally establish hierarchy and maintain flock harmony. When pecking becomes aggressive and persistent bullying, weaker or sicker birds are targeted.

Many animals are habitual, including chickens. They rely on routines; therefore, any interruption can cause stress-related behavior. Stress in chickens can cause aggression and bullying. 

Sick hens behave differently because of weakness. Their new habits interrupt the routine, leaving them more vulnerable to bullying than other healthy chickens.

Understanding these chicken behavior traits helps explain bullying, mainly when it includes sick chickens.

So, Why Chickens Bully Sick Chickens?

Here are a few common reasons behind this problem:

Disease Detection: Chickens naturally sense illness in their flock. One sick chicken generally behaves, looks, and moves differently from the others. Chickens may be bullied because of these changes.

Chickens are highly observant and can identify feeling sick chickens by smell, physical expressions, or vocalization. The pecking and harassment are because they address this suspected danger to the flock.

Remove seen weakness: Chickens follow “survival of the fittest.” Any weakness or weakness can harm the flock. Chickens instinctively remove dangers to the group’s well-being. 

Sick chickens may appear weaker and less able to protect themselves or compete for resources, making them easy targets. Chickens attack weaker ones to maintain flock strength and vitality.

Small space according to flock size: More space in chicken coops or runs can stress flock members. Stress from confined living may increase dislike and bullying. A healthy chicken can be bullied, but a sick chicken is especially vulnerable. 

Being an easy target encourages bullying. Chickens need space to move and create their territories to prevent stress and bullying, especially when unwell.

Chicken competes for resources: Chickens compete aggressively for food, water, and shelter. A sick chicken may need more energy or the ability to compete for these resources.

This might be considered a weakness in a competitive flock, and other hens may deny the sick bird access to essential nutrients. Bullying can involve pecking and solitary existence.

Environmental Changes: Coop or run changes might cause bullying when a chicken is unwell. Adding hens or changing the layout might stress the flock and disturb its order. Their flock mates may target sick hens or roosters due to their sensitivity to these changes.

Territorial Disputes: Sick chickens might disturb the coop or run established territories. New or unfamiliar chickens may cause territorial issues involving the sick chicken. As chickens compete for territory and dominance, bullying can occur.

Lack of friendliness: Chickens are friendly pets, making introducing new or sick birds into a flock challenging. Chickens may bully to establish their social hierarchy and maintain flock order. This is especially difficult for sick chicks to fit in a new flock.

Here are a few common signs and symptoms of chicken bullying chickens:

Injuries on the chicken body: Chicken bullying is most apparent when the tortured bird has visible injuries. The injuries usually appear as peck marks, scratches, or deep open wounds. 

Here are a few of the best wound care sprays for chickens.

Chickens bully by hitting their victims’ feathers, combs, wattles, or skin. Untreated injuries can cause blood loss, pain, infections, and ultimately death.

Feather loss in chickens: Chicken bullying often causes feather loss. Bullied hens typically have their feathers plucked. 

This makes regions of naked skin susceptible to freezing temperatures. Bullying can be seen in feather loss, so keep the feather-losing flocks separate from healthy ones.

Self-isolated bird: The bullied chickens generally withdraw themselves from the flock. Their main activity is hiding or avoiding other chickens. 

The bullied chicken may get more stressed and anxious due to isolation. A chicken that constantly separates from the flock is a sign of bullying.

Loss of appetite: Stress from bullying might impact a chicken’s appetite. Bullied chickens may lose their appetite and eat less. This might cause weight loss, nutritional deficits, and weakening in the chicken.

Reduced egg production: Bullying can also reduce chicken egg production. Stressed and poorly treated hens may produce fewer eggs. This decline in egg laying indicates stress and affects poultry owners commercially.

Stressed chicken: In addition to losing feathers, stressed chickens may pluck their feathers excessively. This habit often helps them cope with stress and discomfort. It can cause self-harm and worsen bullying.

Pacing and Angry Behavior: Bullied chickens may pace, move, and be restless. Bullying may make them uncomfortable and unhappy, which might harm their health.

Impact of Bullying: From Chicken Bullying Hen to Chickens Bullying New Chicken

The significant impact of chickens bullying sick chickens is detailed below:

Injuries in bodies: Physical injuries are the most apparent consequence of chicken bullying. Pecking, scratching, and aggressiveness can cause bruising, wounds, and blisters on the skin. 

These injuries can cause infections, blood loss, and long-term health issues if left unsupervised. Bullied chickens may suffer long-term pain and suffering.

Reduced egg production: Bullied chickens are stressed, which reduces their egg production. Stress-induced hormonal changes may significantly reduce egg production. 

Small backyard chicken keepers and large poultry farms may suffer from this, impacting profitability.

Stress: Chickens bullied experience high stress. Stress harms a chicken’s immune system, digestion, and overall health. It is because the bullied chicken is more sensitive to diseases and less adaptable to environmental changes.

Growth retardation: Bullying can lower flock productivity. Stressed and injured chickens are less likely to eat feed, and growth retardation is seen in the individual bird.

When a chicken does not gain weight in early life, their growth permanently stops at a particular size. 

Potential mortality: Extreme bullying can kill the chicken. Physical trauma, stress, and weakened immunological function may kill the chicken. This has ethical and practical ramifications for animal welfare and flock management.

The Extreme Case: Chicken Bullied to Death

Bullying a chicken to death is one of the saddest things that may happen in poultry farming. This painful outcome usually occurs when continuous and cruel bullying targets a weak or sick chicken. 

This severe example highlights the serious effects of unmanaged flock hostility and the importance of caregivers in keeping their feathered friends safe and happy.

Imagine a coop full of chickens clucking and interacting. However, a weak chicken may stand out. This weak chicken becomes the object of harsh and constant bullying, being pecked, harassed, and deeply injured.

Regular pecking can cause cuts, scrapes, and bleeding hole-like wounds. To prove their power or eradicate seen weakness, chickens are prone to harming their fellow flock members. 

If not treated immediately, these physical injuries can cause infections, blood loss, and long-term suffering for the bullied chicken.

The continuous aggression injures the chicken and creates suffering and stress. Under extreme stress, the bullied chicken may stop eating and drinking. 

Refusing necessary nutrition can cause starvation and dehydration, causing the chicken’s long and painful death.

Witnessing such a horrible result is painful for those who care for our feathered friends. It highlights the importance of knowing about and controlling poultry bullying to prevent aggression and protect flock members. 

Chicken raisers must be aware of flock interactions to spot bullying before it increases. This requires monitoring individual hens for isolation, visible injuries, and changes in eating and drinking patterns.

Creating a stress-free, spacious, and socially balanced setting can greatly prevent bullying.
