A friend of mine has 18 chickens who all get the same food. One of her chickens lays an egg that tastes horrible. She describes it as you were tasting someone's bad halitosis. She figured out which chicken it was & it constantly lays these horrible tasting eggs. Is there a reason for this & can anything be done to change it. She is sending me a photo but from her description, I suspect it is a Rode Island Red.
