There are several reasons why a chicken may have died at 3 years old. Chickens can hide symptoms of illness, and death can come suddenly, with no obvious signs of distress. This is known as Sudden Chicken Death Syndrome, which is most common in fast-growing broiler breeds and male chickens. Other causes of sudden death in chickens include heart attack, heart failure, and predators. Chickens can also die from old age, with the average lifespan of a chicken being between 3 to 10 years.

Old age
The average lifespan of a chicken is between three to eight years, with some chickens living up to 12 years. However, it is not uncommon for chickens to die at around three to four years old due to old age. While the exact cause of sudden death in chickens is often unknown, there are several factors that can contribute to their demise.
Chickens are susceptible to various health issues as they age, such as heart problems, liver disease, and cancer. For example, older hens may experience internal laying, where eggs become stuck or break inside them, leading to sepsis or other infections. Additionally, chickens can suffer from Marek's disease, leukosis, and lymphoid leukosis, which can be fatal.
Genetics and breeding practices can also play a role in a chicken's lifespan. Inbreeding is common in chickens, and this can lead to weaker genetic traits and increase their susceptibility to certain diseases. Commercial broiler chickens, which are bred to grow rapidly and gain weight quickly, are at a higher risk of developing Sudden Chicken Death Syndrome due to the strain on their hearts.
Environmental factors, such as diet, lighting, and exercise, also contribute to chicken health and lifespan. A poor diet, lack of exercise, and overexposure to natural and artificial light can strain a chicken's body and lead to sudden death.
While it is difficult to determine the exact cause of death in your 3-year-old chicken without a necropsy, old age could certainly be a factor, especially if your chicken was slowing down and had stopped laying eggs regularly. It is important to remember that providing a healthy and caring environment for your chickens can help prolong their lives and prevent premature death.

Heart attack
It is difficult to determine the exact cause of your chicken's death without veterinary expertise. However, based on the search results, heart attack or heart failure could be a possible reason for the sudden death of your 3-year-old chicken.
Chickens are prone to heart-related health issues, and heart failure is a common cause of sudden death, especially in roosters or fast-growing breeds. It can occur at any age and is often undetected, as chickens are adept at hiding their illnesses. Lack of exercise and an unhealthy diet can contribute to heart issues in chickens.
In some cases, microscopic lesions in the heart muscle, known as vacuolated sarcoplasm, cytoplasmic eosinophilia, and nuclear pyknosis, have been found in chickens that have died from SDS. These lesions indicate a metabolic disorder that may predispose birds to cardiac arrhythmia.
To reduce the risk of heart-related issues in your chickens, it is important to provide them with a good diet, low-stress environment, clean housing, and adequate exercise. However, it is important to note that not all causes of sudden death are preventable, and chickens can sometimes pass away without any apparent symptoms or warning signs.

Poor diet and rapid weight gain
Chickens are susceptible to the adverse effects of an unhealthy diet, just like any other animal. A diet high in saturated fat and cholesterol can lead to obesity and related health issues in chickens. Chicken, in particular, has been identified as a high-fat product, with modern organic and broiler chickens providing more energy from fat than protein. This contradicts the common belief that chicken is a leaner option compared to other meats.
Additionally, rapid weight gain in chickens can put extreme stress on their hearts, leading to heart attacks or heart failure, which is a common cause of sudden death in chickens, especially males. Commercially raised broiler hens, which are bred to gain weight rapidly, are often affected by this. The excess weight can be too much for their hearts to handle, resulting in sudden death.
Providing a healthy and balanced diet for your chickens is crucial. While the specific dietary needs may vary depending on the breed, age, and activity level of your chickens, ensuring they receive adequate nutrition is essential. A diet rich in protein, vitamins, and minerals is ideal. It is also important to monitor their weight gain to ensure it is gradual and healthy.
In the case of your three-year-old chicken, it is possible that a poor diet, high in saturated fat and cholesterol, may have contributed to its early death. Additionally, if your chicken experienced rapid weight gain, it could have put excessive strain on its heart, leading to a heart-related issue. To prevent this in the future, consider consulting with a veterinarian or poultry specialist to design a balanced diet plan for your chickens and ensure they maintain a healthy weight.

Inbreeding
While there are many reasons why a chicken might die at 3 years old, one potential cause could be inbreeding. Inbreeding in poultry is the mating of closely related individuals, such as cousins, sire-daughter, or brother-sister. This practice can have both positive and negative effects on the offspring.
On the one hand, inbreeding can increase the number of individuals that are homozygous for a trait, leading to a higher expression of recessive traits. For example, inbreeding Leghorns with nice tails will likely result in offspring with even better tails. Additionally, in the past, inbreeding was a widely accepted practice in exhibition poultry, and any negative consequences were likely to have already been exposed and eliminated.
On the other hand, inbreeding can also bring negative traits and health issues to the surface. If a bad trait or health issue is discovered as a result of inbreeding, it is important to take action immediately and eliminate all carriers of the undesirable trait through experimental breeding. While inbreeding is not always detrimental, it does carry a small risk, and it is important to carefully consider the potential consequences before engaging in the practice.
In the case of a 3-year-old chicken's death, inbreeding could have potentially played a role by increasing the likelihood of negative health issues or undesirable traits. However, without further information, it is difficult to determine the exact cause of death and whether inbreeding was a contributing factor.
To prevent sudden death in chickens, it is recommended to look out for signs of illness or distress, such as laboured breathing or gasping for air, and to consider factors such as temperature, stress, diet, and flock dynamics. Additionally, performing a necropsy, or poultry autopsy, can help determine the cause of death and provide closure to the chicken's owner.

Illness or disease
While it is impossible to know the exact cause of death without a necropsy, there are several illnesses or diseases that could have caused your 3-year-old chicken to die.
One possible cause is Sudden Chicken Death Syndrome (SDS), which is most common in fast-growing broiler breeds and male chickens, but it can also occur in female birds. SDS has been linked to metabolic origins, but factors such as environment, genetics, and nutrition can also play a role. Poor diet, rapid weight gain, and lack of exercise can contribute to SDS by straining the bird's body and causing heart issues.
Another possibility is that your chicken succumbed to a disease that commonly affects older hens, such as internal laying, egg yolk peritonitis, oviduct cancer, or liver disease. Marek's disease and leukosis are also mentioned as causes of death in older chickens, with tumors forming as a result.
In some cases, chickens may appear healthy and show no signs of illness before their sudden death. This could be due to their expert ability to hide symptoms, or it could be related to heart issues, as heart attacks are a common cause of sudden death in chickens, especially in male chickens.
While less common, other diseases such as avian influenza or lymphoid leukosis could also lead to the sudden death of a chicken.
