Why Does A Chicken Live That Long?

The major reason why a chicken lives that long is because the life cycle of a chicken takes about a minimum of 7 years to a maximum of 9 years to get completed.

However, with advancements in veterinary medicine and veterinary science, scientists found suitable conditions for chickens to survive for a longer duration of time. Moreover, with developed and improved knowledge about appropriate chicken care, good feeding habits, and all other survival situations, the average lifespan of the chicken can be increased from 3 years to about 5 years.

Chickens are generally not more vulnerable to survival problems like predators and food shortages. When taken proper care of, provided safe and suitable shelter, a healthy diet, and an attentive owner, a chicken can easily live up to as long as 12 to 15 years in captivity.

Moreover, because chickens are a part of the food chain at a very low level. That means, the animals which thrive upon other animals as food for their living, generally make chicken their prey. So, as a result, chickens fail to live long.

Unlike the wild chickens, the chickens who live under captivation can live for as long as a span of 12 years. This is so because these chickens have no stress to survive, they don’t have to struggle for food or fight predators. Such chickens are provided food and a good environment, they are far away from predators and thus, they have a long lifespan of 10 to 12 years.
