Battery Cage Hens live the most atrocious of lives, in ongoing suffering and discomfort so that eggs can be produced for a few cents less per unit. Please - if you aren't fortunate enough to be able to keep your own hens: choose battery-cage free, Free Range Eggs. Where possible opt for packages with the most stringent certifications in place. In Australia, this means the RSPCA seal.
Hens deserve better. And -- because we are what we eat -- our bodies deserve better, as well.
