wrinkly egg

She may have laid a double yolker there. And the shell looks a little thin. Anyway, back to basics, are they covered? Do you offer crushed oyster shell free-choice always available? Does she eat a balanced layer feed, with adequate protein?

If she's getting all that and she's looking healthy and vigorous, it could be a temporary hitch in her shell gland workings that will work itself out. Here's an article about misshaped shells:

I have one or 2 hens that lay some funky eggs from time to time. I call them dinosaur eggs, because they are totally wrinkled for 2 or 3 days. Not sure why mine do it, but it stops after a bit, and then will happen again for a few days. They are usually really big eggs--- my thoughts are that if they're double yolks, or slow going through the egg canal, that maybe they "mold" into the shape of the surrounding blood vessels, and stuff, and since it's slow moving, the shell hardens while it's sitting, instead of when it's moving through the canal ( why it looks so smooth usually) ? I dunno, just my own thoughts-- thinking of how clay or paint would dry-- moving versus sitting still in an enclosed area.

 

My Golden Comets lay eggs such as these quite regular.... I always thought that it was just that my hens egg had broken inside and then she repaired it and laid it! but if this is an illness of some sort I sure would like to know!

 

That doesn't seem like an issue to me. If the entire egg looked like a crumpled paper bag and it was always like that, I'd say a possible bout of infectious bronchitis went through your flock, but that doesn't look like that type to me.
