People love chickens that are “vegetarian fed.” But chickens are not vegetarians.

62. I'm pretty sure that was the original point of this advertising.

Many chickens were being fed chicken meat "byproducts" including male chicks (useless for egg laying) and old chickens that were no longer laying their quota of eggs. These are the same sorts of practices that endangered humans with "mad cow" disease and other horrors.

The chickens a few of my siblings raise are fed "vegetarian diets" mostly, kitchen leftovers occasionally, but they also live outside and have easy access to insects.

They are, as others have said, little raptors. When I was a teen I picked up a board in the family garden, and the chickens came running, as they usually did whenever anything in the garden was disturbed. Unfortunately there was a mouse nest under the board with pink baby mice... it was a very ugly scene, bloody carnage all around my feet.
