The Trader Joe boxes are green in color on top and have "Fertile Eggs" in the title. They're kind of hard to spot, though, because usually they're located waaaaay down low in the corner of the egg case in four out of five stores I've gone to.
The point is they ARE refrigerated store-bought eggs..... The hatch rates may not be great, but there are at least hatchings! And then, as in my last two dozen, sometimes not.... (yolks in most were pre-scrambled due to rough trucking out of state)
