Egg Shells

[Curtis Rayborn]

Has anyone had eggs produced with this kind of shell configuration and what is the cause/fix for it?

Weird eggs happen sometimes. Here's a guide to egg quality issues that includes corrugated/wrinkly egg shells like this one: https://www.backyardchickens.com/articles/common-egg-quality-problems.65923/

I wouldn't worry if it's a one-time or infrequent occurrence, but if it starts happening more often, that article includes multiple possible causes.

It's called a corrugated egg, there are many causes but I'd you only get one, it's probably just a hiccup in production.
