Further to the questions on chickens' eggs (size and fertilization)(Jan & June 1999), I was wondering why chickens "waste" so much energy laying fully formed, unfertilized eggs. Mammals get rid of small unfertilized eggs and a slight thichened "just in case" endometrium, thus not wasting energy. Chickens don't: they make the whole package and then discard it. Do any other birds also lay eggs continuously?
