I'm finding wonky eggs. They look cracked but aren't. See the pics?

I believe all of these eggs are coming from my girl, Kyle who is 1/2 Buff Orpington and 1/2 EE. Recently, we've been finding these eggs getting weirder and now appearing to be cracked but aren't. I don't know what's causing this. Her diet has not changed. She gets high grade feed to eat at will, is free range and I give her fresh produce regularly. She also gets a lot of yogurt and I keep the water clean, fresh and full. There is a very, very slim possibility that my new girl who is a purebred Ameraucana is laying but I've never caught her in the act. She hatched on 3/31/14. The girls I got at the same time as her are laying, she is not. They are not the same breed and lay brown eggs so no confusion there. I may have to confine that stinker and see what in the world! Anyway, please see my posted pics. I'd love some input.
Thank you.
Ok, I can't figure out how to post pics. Standby.

Definitely agree with your comment there about having to confine to find out who's laying these eggs. Good luck posting pics.

Best wishes.
