Well I have read books and I am sure I can find studies that would disagree with Weston on those facts. I personally don't believe him.
I thought this was funny.
I recently picked me up some silkie chickens, the lady who I bought them raises all sorts of heritage breeds, she often shows them to schools and such. She was telling how many kids were absolutely shocked that eggs came from chickens. They thought eggs came from the grocery store.
