This question is inspired by the claim that the modern breed of chickens has nothing unhealthy in them because they are genetically bred to be like this.
The fact is:
Some people are concerned about the nature of the modern broiler chickens, especially when they see the featherless breed. These chickens are different not because they are genetically modified. According to the National Chicken Council, no chickens are genetically modified in the United States. Instead, they are raised from a natural process of selecting and crossbreeding to achieve better qualities. Modern broiler chickens grow three times faster than the traditional breeds of chickens, and the fast growth leads to the chickens’ health problems. The chickens’ bones, joints and internal organs may face the risk of breakdown. Common diseases include ascites, heart attacks, lung collapse and leg problems. Obesity is the cause of most of the problems just like the case in the human beings. When broiler chickens reach 6 weeks old, 90% of them become so obese that they can no longer walk. As a result, it is arbitrary to claim that these chickens have nothing unhealthy in them. In fact, they are suffering from serious health problems.
