Factory animal ethics.
Still a problem, because factory animals aren't survivable in the wild, they'd die of starvation or be eaten pretty much immediately. They aren't like wild animals. Most wild animals end up eaten by another animal or dying of starvation anyway - life expectancy is short.
I remember a report on chickens (forget if it was the Los Angeles Times or the Wall Street JOurnal). The journo visited a "free range chicken" farm and noticed the "free range" was empty and all the chickens were packed into the coop. The doors were all open. The farmer told him, "We can give them the space but we can't make them use it - they just like togetherness".
