Since starting low-carbing, I increased my egg consumption from “every now and then” to sometimes dozens per week; they are my main protein source. This made me much more concerned about the production of the eggs, not so much from a health standpoint (I’m just not that much of a purist), but rather from concern about the life quality of the chickens. I happened to come across a Washington Post article that talks about how the various terms used to describe production (organic, cage-free, etc.) are not really meaningful. It had a link to a website that lists egg companies and rates them on their practices. I was disappointed (but not really surprised) to see that the eggs I’ve been getting at Costco are not highly rated, but I was really happy to see that the (unexpectedly inexpensive) eggs I got at Natural Grocers yesterday are.

On a side note, when I switched to cage-free eggs, I was shocked by how brittle the shells are. I’m a pro at cracking eggs, but I’ve found it difficult to not get shell shards. The eggs I got at Natural Grocers have shells that are far thicker and easier to crack without losing shell bits.
