Thanks Susie. That was interesting (esp. for an Aussie).

Some of the supermarket egg choices we have here:
  • Barn raised
  • Free range
  • Omega 3
  • High-folate
  • Vegetarian
  • Organic
  • Generic (probably battery hens)

The colour of egg shell is not segregated in to a category. Both brown & white eggs are sold.
When I had to buy some supermarket eggs for the 1st time in ages, nearly a decade ago, I was dumbfounded by all the choices. I literally could choose the living quarters & their diet by my egg selection.
