One of my hens is laying eggs that are larger than the other gals (generally 2 and 1/4 ounces, sometimes 2 and 1/2 ounces), light brown but with white specks on the egg shell, and when you crack open the eggs, the whites are as thin as plain water. The yolks are normal, except they sometimes break a little easier than other yolks. But it is as if the egg white was nothing but plain water. My other hens lay normal eggs with the normal thick egg white liquid. Why is this happening? I can now tell the watery egg before I even crack it open, because it is larger and looks different than the other eggs. What should I do about it? Right now, I'm throwing her eggs out, because I don't trust that watery egg white.
