Ah, ok. I got excited and read the posts too fast. *ha* My fiance's dad eats fertile eggs, and they are store bought. I will ask him where they get them.
Gracefulbantam shipped me eggs last week, when it was below freezing for several days. After 7 days we checked them, and almost all are fertile and developing! I guess if the eggs weren't in the fridge too long, then they are still capable to growing.
How pricey were the eggs? I would guess that they're RIRs, that seems to be pretty common for brown egg laying.
