I know we make fun sometimes of people who don't know anything about eggs and how they are "created" so don't yell at me too much for this one! I had always been told that an egg with a thick membrane (when you cracked it) was an old egg. I am cracking eggs the day they are laid and I can't get over how tough the membrane is! Is the old wive's tale wrong? Or is it that my hens are still young??
