Raw ground beef from the store is a very good source of Salmonella and other ungood bacteria. That's why we cook it! Infecting your chickens is a bad idea, for their eggs, meat, and interactions with your family. At least cook any meat that you feed them! Mary
This got me wondering about it. I was under the impression that things were better in the beef industry then when my parents grew up.
I was wrong.
