Today I got a strange egg from one of my red sex-links or my black sex-link. All of my 4 girls are about 2 years old and are not currently molting. This egg is very long, light colored, and rough. The weird thing is that you can chip off the light rough stuff and there is a darker color underneath it. Should I be concerned about the hen that laid this? My thumb is pointing to the area where I chipped some of the rough outside off. This is it compared to a regular egg.
