I just found another grocery store source for fertile eggs in Sonoma county, California.
It is Community Market, an organic store in Sebastopol and Santa Rosa. They have a brand of fertile eggs called Red Rose Half Acre, from a farm in Windsor, 20 miles or so from Santa Rosa. These fertile eggs cost $8.99 a dozen, and the colors are varied. The carton I got had a blue-white one, a tinted one, an olive one, three greens and the rest were brown. When I candled them, I found only a few porous shells, and the air cells were unruptured, not rolling, and nickel-sized. The Julian date on them was 088, so they're a little over a week old.
The Whole Foods store at Coddingtown in Santa Rosa has Alexandre Kids brown eggs, rumored to be fertile, coming from Corning, CA. When I looked them over, I couldn't tell them from any other carton of pale brown eggs. (Probably will hatch Red Stars.)
There are some shipped Ameraucana eggs coming to me in a few days, and I plan to incubate my Red Rose and Rock Island eggs with them, and post about hatch rates here.
