What is the difference between organic chicken and intensively reared chicken?

Organic approaches to raising farm animals don't use resources that aren't available in the immediate area or that involve chemicals and synthetics. Intensive approaches do. As an example, intensive production of farm animals may rely on growth hormones. As another example, it also may involve genetically modified organisms. The GMO may be the food that the farm animal eats. Or it may be the animal itself. As still another example, intensive production may draw on resources that are made off site. The consequence is a lack of control over a product's make up, pricing and quality.
