I called the Puget Consumer Co-op today, thinking that as purveyors of organic everything, they'd carry fertile eggs. Nope. The manager said their customers thought it was squicky, and they couldn't sell that kind of eggs in enough volume to be able to order them (he had to order 15 dozen at a time, or something).
But he said Safeway carries the 'O' Organic brand (we do have Safeway just down the street - I can ask them when they get egg deliveries to buy the freshest they have) and also there are the farmer's markets, I can check with them if anybody sells eggs. I'm on the hunt!!
