While many foods seem stretched out in Siem Reap, almost all the eggs sold in Cambodia come from caged farming: http://en.wikipedia.org/wiki/Battery_cage

These eggs are produced free range and their hens live with a sense of dignity, rare in this neck of the woods or for that matter anywhere. Organic doesn’t mean very much these days when you visit farms and see the lifestyle of egg producing hens.Eggcellent in Siem Reap has been crowned with quality eggs.
