What is wrong with this egg? Is my chicken okay?

[OhDangBro]

Hey all,
Can anyone tell me what is wrong with this egg? It is still very hard, extremely light in color but has like splotches of hard parts? Some back info: My chickens are about one year old, all the chickens seem very healthy, it has been a rough winter here and up until a couple days ago we've had snow covering the ground for about three weeks(it's all melted now), ALSO yesterday a hawk tried to swoop down on my girls, everyone was safe, but they got separated and some ended up hiding in a bush, the garage and the coop. Could this have been from nerves?

Could be. If the attack occurred while the egg was in her shell gland, I can imagine that the natural clenching of her muscles and the adrenaline from panic could perhaps cause such an egg. Keep an eye on her and her eggs and see if the problem persists.
