What's the difference between free range and factory farming?

There are a couple key differences between raising organically grown livestock and raising them in a factory farm system. One of the most important differences is the food the animals are served throughout their lives. The definition of organic farming is to grow plants and livestock without them having been fed or treated by anything containing chemical additives. In contrast, the idea of factory farming is to produce a large yield of animals in as short of time (and with as much meat on them) as possible. Therefore, factory farms rely heavily on feed that has been modified chemically to produce a large quantity of "beefy" livestock in a hurry. The second biggest difference is the living condition in which most animals are raised. Factory farms are notorious for being small, dark and desperately overcrowded spaces that animals have barely any room to move in. *

Not much as "Free Range" is an undefined term that means animals are not in cages but they can still be crammed into barns as is done with all chickens raised for meat. people think it means the animals are out on grass but rarely is this the case with free range livestock. All of the eggs you find in grocery stores that are cage free or free range are from hens that still live in huge barns and never go outside.
