You know, chickens reproduce on their own, with no more required energy input than chicken feed, water and sun. They lay delicious eggs and they are themselves quite tasty. They have been kept long before modern technology and in those days were largely fed on scraps and trimmings.

I predict that no factory made meat will ever be able to succeed with as little energy input as a chicken, and that people who believe that it would be greener to eat factory meat are fooling themselves.
