Will store bought chicken eggs hatch?
If you're getting your eggs from a supermarket, they won't hatch. This is the case with eggs you get for eating from almost any source.

Hens lay eggs even if they haven't been, umm, mating with a male. Any egg laid in those circumstances will never hatch because it's unfertilized, and that's the standard practice for any commercial egg operation.

Now if you have a free ranging hen and a rooster too, and they're not kept apart, then yeah, you could get a fertilized egg. And that egg needs to be kept properly warm to hatch.
