(Warning: video is totally gross). Via this SF Gate item, a Chicago-based animal rights group called Mercy for Animals shot the video above of baby chicks being ground up alive at an Iowa chicken processing factory. It's pretty disgusting, and reinforces a personal decision I made to avoid consuming eggs that come from this sort of place:
Hy-Line admitted to the Associated Press that "instantaneous euthanasia" (e.g. grinding up male chicks) is a standard practice and claims that it is also supported by the animal veterinary and scientific community. (Male chicks are less valuable because they can't lay eggs or be raised quickly enough for meat.) Mercy for Animals estimates that 200 million male chicks are killed annually and United Egg Producers confirmed this figure.
