And here's some more from NASA:
Freeranger Eggs is a free range egg farm at Grantville in the southern Australian state of Victoria. Our hens are never locked up, they are fed a natural diet of grains with no additives - and they are not beak-trimmed. The only reason for removing the top part or even the tip of the beak is that when hens are confined in small spaces and in large numbers they often become aggressive and attack each other. On a true free range farm with plenty of space, all birds have full beaks.
