Meat birds are USUALLY raised w/o free ranging them. Its part of what gives factory meat bird production such a bad name.
Its not as bad as it once was - but it still tugs at the heartstrings of many.
/edit when you get right down to it, pasturing or free ranging increases the risk of disease/injury/predation, slows the rate of weight gain, toughens the meat - exactly what shoppers don't want in a supermarket bird - and driving up costs for producers.
We BYCers pasture/free range for lots of reasons - better flavor, potentially healthier less fatty birds, because it seems more humane to us, etc. Generally, it doesn't affect the cost curve much - what is gained in "free food" is offset by the additional energy needs of an active bird. This is a case where tractoring is probably better than free ranging in most metrics.
