Very weird eggshell

[ponzi]

one of my chickens-I have eight- Laid a very weird egg. Normal hardness, color, but quite wrinkled. Has anyone seen one like this or have any idea as to What may be going on?

'Corrugated shell'.
Could be a glitch, or a faulty shell gland, or disease.
May never happen again.
It's fine to eat.
