Very few animals besides apex predators in the wild live long enough to die of old age. Rather they die from starvation or disease or are eaten by something else. Life on industrial farms sounds terrible, for sure, but death in nature is also terrible, to the point that I'm not sure it's a mercy to "set them free".
