Beginning with the basics, chickens are domesticated birds that are most often raised as poultry for meat or eggs. Chickens are descendants of the wild red junglefowl and are considered omnivores as they will eat a varied diet including insects, seeds, and greens. The lifespan of a chicken depends on the purpose it was bred for. For example, chickens bred for egg production generally have a shorter lifespan than those bred for meat production. However, on average, a chicken will live between 5 and 10 years. In addition, chickens have been known to carry certain diseases. These diseases can be transmitted to humans through contact with chicken feces, contaminated food, or close contact with infected chickens. The most common disease that chickens can transmit to humans is salmonella. This occurs when chicken meat is not cooked properly and can lead to food poisoning. However, as long as chicken is properly cooked, it is healthy and safe food to eat. It is very famous due to its protein content as well as being low in fat. In addition, chicken is a good source of essential vitamins and minerals such as phosphorus, selenium, and vitamin B6. This is why chicken is often included in diets for athletes and people looking to build muscle without gaining too much fat.
