I'm wondering what's going on with my Easter Egger....she had been laying normal eggs up to 2 months ago when she started her molt. Then she was laying eggs without a shell. Just yesterday she layed a weird shaped egg and now today another. I'm giving my hens yogurt along with layer pellets everyday and they have free access to oyster shell. My other hens don't have a problem. Can someone shed some light on this for me??
