Ridges and grooves on egg?!?

[KNelly]

What can cause this? I have 2 chickens that lay. Since I added 2 new girls to the flock they went from consistently laying to I'm lucky if I get 1. Nothing has changed other than adding the 2 new girls which isn't anything new to my flock. The 2 new ones are only 10 weeks old so I know they aren't picking on the older ones. My easter egger went from green to blue eggs and my leghorn is now laying eggs with ridges and grooves. Other than eggs their behavior hasn't changed and they don't seem the least bit sick so what could be going on? Can stress cause that? Will it eventually go away?

Stress can cause a lot of issues including egg changes.
