You can get two dragon eggs on a non cheats survival world :I

Who remembers the day when they first beaten the dragon , well if u have u must know that beating the dragon for the first time give you the most delicate and precious object the dragon egg but if you were to res pawn the dragon in 1.16.1 and you had already beaten it before , well to my surprise when I re-beated the dragon he dropped a other egg splendid..... wait that not supposed to be like that XD .
