Holes in my eggs!

[finneasW]

Newly laid eggs keep coming up with holes in them, and I’m worried! I had a rat problem due to a hole in my duck’s coop and I am thinking maybe they found another way in again? The holes all are the same shape each time. I’m just hoping it isn’t another duck poking holes. The yolk doesn’t seem to be eaten. Any advice? What does this look like to you?

Can things like Jay's get into your coop?

No, I also haven’t seen many near my house at all. The most common bird that lives in my backyard are sparrows.
