Symptoms of a sick chicken flock.

Get to know some symptoms of a sick chicken flock and what to do if they aren’t acting normally. Their health affects the entire supply chain, so it is crucial to know if the birds are sick or tired of the heat stress. 

Whether it’s just one bird that’s ill or an entire flock that’s affected, it’s always a good idea to know the symptoms of a sick chicken and contact your vet for confirmation.

You’ve heard it before: “Feed them, water them, and make sure they’ve got plenty of space to move around in. If they don’t seem happy, then something’s wrong.”

What Does a Healthy Chicken Look Like?

There are several clinical signs which will indicate the health status of your poultry birds.

Facial Appearance.

The first sign to look for when determining the state of health of your chicken flock is facial appearance. A healthy chicken should have a bright, shiny head, wattles, and comb.

A normal facial appearance indicates that the chicken is in a good state of health and that the digestive system of the bird is alright.

Diarrhoea is a sign of digestive disorders; any chicken suffering from a digestive disorder will look listless without a normal appearance.

Good Appetites

Appetite is a good indicator of the health of a chicken. When a chicken refuses to eat, it may indicate an underlying medical problem like a digestive disorder, respiratory illness, or a muscle issue in the neck or head.

Posture and Appearance

A healthy chicken carries its head high and alert with a variety of cackling sounds that indicate the bird is in a good state of health. They should look plump with an overall healthy appearance.

In addition, they should have shiny and not ruffled feathers, bright feet, and a strong gait. 

Attention to Surroundings

A healthy chicken shows interest in its surroundings; it’s always alert and responds to environmental stimuli.

They’re intelligent and have an instinctual desire to move around, explore their environment and interact with other chickens. Chicken also has a unique ability to feel pain.

This means that they have a much higher sensitivity to the environment than most other farm animals.

They are constantly on the lookout for predators and forage for food. When they’re not doing one of these things, they’re laying eggs and producing feathers. 

Breathing and Respiration

For a healthy chicken, breathing should not be too erratic and should be noiseless. It should be regular with no signs of distress or panting.

If a chicken appears anxious and restless it may be a sign of respiratory problems, diarrhoea, or colic. If you notice abnormal breathing, consult your veterinarian for treatment options.

Absence of discharge

Healthy chickens do not have any discharge coming from their eyes. It is normal for the eyes to be dry and clear.

The chicken’s eyes are protected by a very thick skin called the eyelid. This helps to keep out dirt and other harmful substances. The eyelid is also a good barrier against disease-causing bacteria and viruses. 

Symptoms of a sick chicken flock

Every farmer knows the feeling: when you’re in the middle of a busy day and suddenly realize that your chickens are no longer laying eggs.

This is an especially common problem for small-scale farmers, who often have to make quick decisions about what to do with their animals. 

Listlessness/inactivity

Listlessness or inactivity is a sign that something is wrong with your chicken. When chickens are inactive, it means that they are sick. A chicken’s inactive state means that it is ill.

If a chicken is inactive, it could be suffering from an illness, such as an infectious disease, injury, or even a parasite-borne disease.

Decreased egg production

When a chicken becomes sick, their body diverts resources to fight off the infection or illness, which can lead to a decrease in egg-laying.

There are various common diseases that can seriously impact egg production in chickens. These include respiratory infections, such as avian influenza or Newcastle disease, as well as bacterial infections like E. coli or Salmonella.

Additionally, certain viral infections or stressors can disrupt the hormonal balance in chickens, further reducing egg production. You may also read 6 Tips to Improve Eggshell Quality.

Stress or illness:

Chickens that are stressed or ill may experience a decline in egg laying. Stressful factors can include changes in their environment, predator threats, overcrowding, extreme temperatures, or disruptions to their routine.

Ensure that your chickens have a comfortable floor space and a safe living environment. Discover the essential floor space requirements for broilers and layers.

Parasites or diseases:

Parasites, such as mites or worms, can affect the health of your chickens and subsequently impact their egg production.

Regularly check your flock for signs of parasites or diseases, and consult a veterinarian if necessary.

To address decreased egg production, ensure that your chickens have a proper diet, a comfortable environment, and access to clean water. Regularly check for signs of illness, parasites, or stress.

Comb Discolouration

Your chicken may be sick if you notice a bird with a discoloured comb. The discolouration of the comb can be caused by a variety of illnesses, but here are some possibilities.

• Heat exhaustion,
• Infectious coryza,
• Mites, lice, or Worms can also cause a pale comb.
• Fowl pox

It can also be a sign of lack of oxygen caused by choking a stroke, worms, or possibly avian flu. It could also be an indication of excessive blood flow, such as when the cock is agitated. Contact a vet doctor if you observe any of these symptoms. 

Sudden Weight Loss & Decreased appetite

If a chicken loses weight rapidly and has a decreased appetite, it may be suffering from anorexia. This is one of the first signs of illness. Recognising sick chickens promptly will save you a lot of stress

Loss of weight can be caused by:

•   Parasite-Borne Disease

•   Viral Infections

•   Infectious Diseases

•   Chronic illnesses such as arthritis

•   Diseases of the gastrointestinal tract

If a chicken is anorexic, it is not eating food or drinking water, and the chest (crop) will be hardy. If a chicken is unable to stand, it is in a great deal of pain and suffering. This condition needs to be treated right away, as anorexia can lead to death. 

Irregularities in Eye Appearance

When the eyes of your chicken look tired and sleepy, it might signify a variety of ailments. The eyes of a sick chicken may be frothy, semi-closed, weary, discoloured, or gummy.

However, it might just be an allergic reaction to dust or an excessive ammonia buildup in the pen.

Inconsistent Faeces

Keep an eye on your flock’s faeces; if you notice any inconsistencies, you may be dealing with a range of illnesses from coccidiosis (diarrhoea) or pullorum (white faecal matter), all the way to Newcastle Disease (diarrhoea).

Persistent Scratching

If you notice your hens scratching themselves, they most likely have lice or mites. This is not your typical bathing scrape. External parasites cause them to itch and shake their heads more often, contact a veterinarian for professional advice.

It is vital to get your chicken checked by a veterinarian. Lice and mites are usually very painful and itchy.

They can also lead to other health issues such as anaemia, respiratory disturbances, and even death. If you notice these symptoms, you should take your chickens to the vet doctor.

Breathing / Respiratory disorder

Respiratory disorders or difficulty breathing are other symptoms indicative of the unhealthiness of your chicken.

They can be caused by several things, including stress, environmental conditions, injuries, poor ventilation, and exposure to harmful bacteria and viruses.

In some cases, respiratory disorders can lead to a respiratory disease called “chronic respiratory disease”(CRD).

CRD is a comprehensive term that encompasses a diverse range of diseases that specifically target the respiratory system.

These encompass infectious bronchitis, air sac disease, infectious coryza, Newcastle’s disease, mycoplasma, and more.

The most common symptoms of respiratory problems in chickens include:

•   Rapid breathing

•   Difficulty breathing

•   Poor appetite

•   Chocking

•   Coughing

•   Wheezing

•   A lack of movement

Pasty Vent

This is a condition that happens when the chicken vent has a thick paste on it. There are several reasons for this, including mould, bad weather, and too much calcium. To treat this, make sure that the chicken’s bedding is clean. 

A pasty vent is not necessarily a health problem, but if there are other symptoms present, like diarrhoea, then this could indicate a problem. If this occurs, try to clean out the affected vent with warm water and contact your vet. 

Make sure that the chicken has adequate ventilation, and check its feet. If the problem persists, consult with your veterinarian. 

Deformed eggs

Eggs with various deformities are often found in chickens. They can be caused by a variety of things, including disease and poor nutrition. Most importantly, they should be checked by your veterinarian.

Chickens with their heads down

Chickens that have their head tucked under their body have often been exposed to some sort of injury.

The reason why chickens are likely to do this is that their bodies will protect them by pulling them in close to themselves. They may also be unable to see well enough to move around easily.
