The diet enjoyed by laying hens can greatly affect the flavor of their eggs, says RosemaryHoney. Once in a while, a fresh egg that is not rotten can smell terrible—like manure—and it might have to do with what the hen has been eating. “If you are buying eggs from true cage-free/free-range hens, then they might have gotten into something that makes the eggs smell/taste unpalatable,” says RosemaryHoney. “We have our own hens, and every once in a while, we’ll get an egg that just isn’t right and can usually trace it back to the fact that a couple hens got loose from their pen!” But a smelly egg once in a while is a small price to pay for the superior quality of truly free-range eggs.
