Something for ya'll to mull over.
Commercial layer hens come from a pyramid of parent stock that has been developed by the large poultry genetics companies such as HyLine, Hubbard, ISA, Shaver, etc.
The great-grandparent flocks are at the top of their genetic lines. These are relatively small flocks of several thousand birds that are bred for specific traits. They are kept under lock and key in state of the art, highly bio-secured facilities with bio-tech laboratories. These flocks are the heart of the genetics companies' multi-billion dollar industry.
From these flocks, eggs are shipped out to various countries where grandparent flocks are maintained by company subsidiaries. These grandparent flocks produce eggs that are shipped out to regional areas where the layer breeder (or broiler breeder) flocks are hatched and raised and the eggs for the final F1 hybrid layer hens are produced. (The grandparent/parent flocks are generally two different breeds). The layer breeder flocks produce the millions of hens that lay billions of eggs each year.
Of course at this level it is always cage free production as they are all breeders. It is only at the layer level that they can be kept in cages.
As far as organic production goes, as far as I know, none of the grandparent or parent flocks are raised organically, only the layers producing the table egg for the consumer are raised organically, from the first day of life.
For the previous reasons it would be rare to find commercial organic eggs that are actually fertile. Unless they are coming from a very small and local producer, organic layers are not raised as breeders. There is no benefit to be had for doing so.
It looks like Trader Joe's is selling excess eggs from commercial layer breeder flocks. If there isn't enough demand from the hatchery the extras are being packed up as table eggs. Of course they are cage free (as they come from breeders) and not organic, as there generally aren't any organic layer breeders.
