The real secret to choosing the best eggs at the supermarket

The key is hidden where few consumers look: the code printed directly on the shell. This small number, often ignored, nevertheless reveals a great deal.

  • 0 corresponds to eggs from organic farming,
  • 1 indicates free-range hens,
  • 2 concerns ground-based livestock farming,
  • 3 refers to cage farming.

The lower the number, the more regulated and transparent the farming conditions. This simple indicator allows you to make an  informed choice  when buying, without being influenced by color or packaging. A real habit to adopt for confident consumption.

In short, forget about color and let yourself be guided by the most discreet yet most valuable information: what’s written on the shell itself.  Better everyday consumption  often starts with this kind of detail.
