Yes. Everything underneath the alien skin looked normal. Nice brown shell and a yolk and white when I cracked it open. The white looked slightly cloudy maybe? But other than that, fine.
I just found a freaky egg in my nestbox. The egg itself is almost completely coated in wrinkly dry-looking skin and clear mucous. To my untrained eye it looks like one of my chooks laid part of her reproductive system around the egg.
All my chickens are still walking around, looking quite normal...
