Will store bought chicken eggs hatch?
I'm a bit scared to try it, because I'm not sure what would be worse--cracking open a rotten egg, or having to figure out what to do with a chick.
So how about it? If I leave chicken eggs out, will they eventually hatch if kept at the right temperature?
EDIT - Sorry for the confusion. I was referring to store bought eggs only.
Can you give a bit more info? How old are your chickens? Are they incubating? You have a rooster, I hope? You normally don't have to crack open an egg, so no worries about a rotten egg.
You can sometimes find fertilized eggs in grocery stores (or health food stores). I have no idea if they would ever hatch, though, because they spend quite some time at temperatures not exactly suited to chick development.
@Marti: Chilling a fertilized egg will kill the germ. Fertilized eggs intended for hatching should be kept at about 50-65F until they are incubated. Incubation temperature is 99.5F.
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.
Does chilling the egg, even if it is fertilized, irrevocably kill the embryo?
