Egg with wrinkly, but not soft, shell. <pic included>

[harrisville chicken]

Here's an egg one of my black stars laid for me today. Extremely wrinkly. Not a soft "leathery" shell—it'll crack open. I've had a few this week, but not as wrinkly as this one. The vertical lines you see go all the way around.

She has access to plenty of water and oyster shell. She eats 18% protein pellets and in the last few days all the grasshoppers she can catch (plus all the grasshoppers the little neighborhood children catch and throw over the back fence to the hens).

Should I be concerned?

Thanks

Hopefully not, but there does seem to be some indication that crosses like black stars are a little more prone to egg laying problems.

Let's hope for the best.

We had one that was wrinkled from our rocks that was white and the wrinkles circled from the pointed end half way up. Hasn't happened since.
