Wrinkles in egg shells

[Cindymac]

Have noticed one egg a day that's all wrinkled. None of the 30 girls we have seem sick, breathing is fine, no discharge from their noses, poop all looks good from what I can see. They are kept in a large electric fenced area when we are at work but free range as soon as we come home. Nutrena layer, poulan scratch with meal worms, and veggie/ bread scraps when I have them.

This is just one of the joys of observing chickendom. Weird a$$ eggs. Enjoy!
