Wrinkled Egg

[mctish]

These are pics of an egg I collected yesterday. This is the first time I've collected a "weird" egg. Does anyone know what might cause this? The shell is hard and the egg doesn't feel like it might be empty.
Thank you in advance.

Thank you so much for the quick reply! There is so much information on this site ? I had been looking through it but thought it might be faster to ask.
I think that the among the reasons listed my hen might either be an early layer or stressed, all of them could be in fact, in the past 4 months we've had a house fire and have had to move them twice, and into middle of their first winter. Other than the wrinkled egg and decreased to no egg production they look and act like they are fairing well.
Thanks again,
Tish.

Wow, that does sound like a lot of stress, for everyone! Sorry to hear that.

Hope all turns out well for you!
