Chickens aren't just omnivores, they are scavengers. Free range chickens WILL eat the carcass of dead animals, including other chickens, not just bugs, worms, etc. It is NATURAL.
Cows consuming 'meat' only do it when we create a way that 'bluffs' them into thinking they are eating grain. A cow or horse would not naturally eat meat, even if they are confined in a paddock with a dead cow or horse. They will starve to death first, so it is UNNATURAL.
What is gross to us have no bearing on what is an acceptable food source to any certain animal.
