Every once in a while you will find an egg when you crack it open that has been fertilized ((these have red spots in them)), on a VERY rare occasion. However, MOST of these embyos ((sp??)) have already been killed because of the refrigeration. I also found this online:


"Q: Can you hatch a chicken from an egg in your refrigerator?

A: Yes you can but only if your egg is fertile to begin with. Most of the eggs sold in stores come from large chicken farms where the hens are maintained totally separate from males. No males, no fertile eggs! If you get eggs from chickens that are free range, then there is a good, or at least better, chance that you'll have fertile eggs. An egg can be quite cool BEFORE incubation starts but once it has started, you'd need to maintain a reasonably constant warm temperature. Hope this helps."
