I used to be able to buy Vital Farms pasture-raised eggs at my local farmers market and then suddenly they had a new brand. Davidson Farms and they didn't taste as good and they weren't as yellow/orange as the Vital Farms. I am still very disappointed about it.
So when I can't get the eggs I want I look for a good compromise:
The Happy Egg Co. feeds their chickens non-organic feed in the morning, but then they let the ladies out to pasture, to forage and soak up the sun, at least those who are willing to leave the henhouse. I buy these if I can't get pasture-raised anywhere. They are better than conventional eggs, and their yolks seem to be darker than organic eggs.
