That's a Bad Egg. It's not really a Pokemon egg, but rather, a glitch.
A Pokemon egg cannot die ever.
to get a pokemon egg you must leave two compatible pokemon in the daycare center together. after awhile they will breed an egg

I think a egg with a shiny Pokemon in it is a different color
i think the Pokemon that made the egg with ditto could have an HM move example:surf then it goes to the egg and the Pokemon that came from the egg knows that move.
Any Pokemon with a matching Egg Group can be able to breed. Ditto, with the exception of having its own Egg Group, can be able to breed with any Pokemon, except for Baby Pokemon, Legendary Pokemon (Besides Manaphy, who can be bred with Ditto to get a Phione Egg), and No-Egg grouped Pokemon.
Riolu is 4 generation Pokemon. You can get egg only in Pokemon Diamond and Pearl

just put a male pokemon and a female pokemon that are in the same egg group in the pokemon day care west of striaton city. it will take some time for them to make an egg but the day care man will call out to you once the pokemon have made an egg
