Well the chicken doesnt come from the egg, it is the egg from which it is born, without the chicken the egg wouldnt be an egg, it would just be an empty white shell and easter would now commercially revolve around easter fetuses made of chocolate but thats besided the point. The egg however which isnt part of a chicken comes from the chicken rather than being the chicken from which it came unlike the chicken which is being the egg from wence it came.

So egg

Evolution says egg too
