Genetically Modified Organism Use in the Chicken Industry
The rapid growth rate of broiler chickens makes simply moving from one place to another a difficult and painful task. A 2008 study of more than 50,000 chickens found that by the age of 40 days, over 27 percent of the birds had impaired locomotion capabilities and 3.3 percent were almost unable to walk. This large percentage of lame birds becomes even more disturbing when we consider that chickens whom the farmers considered lame had already been culled due to welfare policies.
The chicken is no longer just a chicken. Depending on what they are bred for, modern chickens are either “layers” or “broilers.” Bred, of course, to lay eggs, layers have been so dramatically altered that they can lay more than 250 eggs per year, while their ancestors in the jungle laid about two dozen annually. They do not grow fast enough to be used for meat, however, which is why all of the non-egg-producing males of the layer breeds are killed soon after hatching. This is where the “broilers” come in.

Because more and more people eat chicken so some they found out away to make more chicken. So they did GMO chicken. They will grow faster and bigger, but this kind of way is bad for human's health.
According to the Roslin Institute, “the nature of the genetic modification is such that it is extremely unlikely that it could have any negative effects on people consuming the chickens or their eggs.”
Beginning in December 2014 and continuing into early this year, outbreaks of bird flu were reported in 21 states in U.S. According to the Centers for Disease Control, more outbreaks may occur in the coming fall and winter. Wild birds can infect domestic flocks that come into contact with their feathers or droppings. Although there are no reported cases of birds infecting humans, there have been cases of people getting sick from bird flu in Africa and Asia, according to the World Health Organization.
