North Americans prefer cleans eggs instead of useful and fresh ones?

Yes, it's a real lack of education. I myself only learned about the benefits of not washing farm fresh eggs 3 years ago.

I am actually very sad to tell you about how chickens live in Canada (these chickens lay the eggs we buy from the grocery stores). Here we have factory farming. The chickens are in tiny cages, 6 birds to a cage, and they have entire buildings full of these cages. The chickens only live there until they are 18 months old, and then they are considered 'expired'.
