May I add that all the male chicks in egg production are gassed or shreddered alive right after hatching, because they're of no use to the egg industry? It's almost impossible to find chicken breeds to buy eggs from where this isn't done. Whether "free range", "organic" or whatever, buying eggs supports this barbaric practice.
I'm from Switzerland and people here are proud of welfare laws for animal agriculture. In practice, that means that instead of 99% of animals raised for food purposes coming out of factory farms (as it's the case in the US), it's only 90%, and the factory farms a bit less horrible. Even though we import a lot of eggs from abroad, where they're from battery hens. That then goes into products with "hidden eggs", where consumers don't even wonder where it all came from. And yes, even a small country like Switzerland, with its 7 million inhabitants, manages to gass or ground 2.3 million male chicks each year. So much for progressive laws.
