Egg looks like someone marked it with blue marker

one of the eggs looks like someone took a blue marker to it. I didn’t do it and my boyfriend said he didn’t do it. This is weird. It came from my austrolorp

Yes but no blue marker of that shade I do have some questionable neighbors. It was weird because she laid he egg yesterday morning. Then I went out an hour later and saw a smaller egg in a separate coop and another hour later saw another smaller egg off to the side of her nest of eggs. I was thinking maybe a neighbor brought an egg over to hatch lol
