Odd shaped eggs

[Cobby]

Hi I've had chooks now for 4 months (2 isa browns & 2 araucanas) and all has gone fine so far until 2 days ago, I got a strange looking egg with wrinkles & another the same the next day & and nothing this morning.
It has to be the isa browns as there the only 2 laying.
Any help or info appreciated.
Cheers.

Hi

This article is a great read and #13 covers corrugated shells ~ https://www.backyardchickens.com/articles/common-egg-quality-problems.65923/
If it's just an occasional egg like this I would not be concerned. Sometimes hens do have an odd blip with their egg laying machines.
