Over the last 50 years, the way food animals are raised and fed has changed dramatically—to the detriment of both animals and humans.
Check your feed bags. Especially chicken feed, as most if not all except Layena feed chickens from their own species. Who wantst to eat meat like this?
“However, most animals are still allowed to eat meat from their own species. Pig carcasses can be rendered and fed back to pigs, chicken carcasses can be rendered and fed back to chickens, and turkey carcasses can be rendered and fed back to turkeys. Even cattle can still be fed cow blood and some other cow parts.”
