Origin
first recorded 20th c. disputed originProbably a humorous antonym of bad egg (“someone whose behaviour is reprehensible or irresponsible; a rogue”). The earliest known usage of the phrase was by Rudyard Kipling in his 1904 book "Traffics & Discoveries": "'Good egg!' quoth Moorshed, and brought his hand down on the wide shoulders with the smack of a beaver's tail."
I was worried about the move, but my new neighbor helped me carry all the boxes; he is a real good egg.
Despite the difficult circumstances, he remained a good egg, consistently offering support and kindness to everyone who crossed his path.
