I had a couple of weird eggs from my hen, "Nettie', this past week. They were frozen and cracked, so I let then thaw and kept them refrigerated for a couple days before I used them. When I cracked them into the frying pan for scrambling, the yolks were hard and stayed ball-shaped! I poked at them, but they wouldn't give. I cut into them, and the texture was like hard boiled yolks! (I didn't eat them) I can't find any posts about this kind of thing. Has anyone come across this? I don't know if the freezing/cracking had anything to do with it, or if they were that way to begin with. She only started laying New Year's Eve, and the only other odd eggs were one with no shell, and one with a wrinkly-looking shell. Thanks!
