free range chicken is indeed a new terminology to many and most of the people will not know what does this mean. It refers to the faring methods where the animals are allowed to roam freely instead of this thing that they are confined in any manner. This is basically done to give as much freedom as possible to the animals. This is done to keep them healthier and this does not keep in account that what ultimate goal they will give whether they will be slaughtered or not. This all comes under the heading of term free range and this must not be confused with any production of animal product.
