yes
no sorry
you cant make legendary eggs.
No you cannot. Legendary Pokemon can't breed (make eggs). Not even with Ditto.
Like any other legendary, you can't get them to make eggs. so nope!
You can breed Manaphy with a Ditto to get Phione.
It is absolutely impossible to get Legendary Pokemon eggs.
Manaphy. If it breeds with a Ditto, you would have a Phione.
The only legendary that can be in an Egg is Phione, which you need to breed Manaphy with a Ditto. But other than that, you can't get any Legendary Eggs.
No, Legendary Pokemon cannot be produced by breeding. No legendary will produce eggs with Ditto, apart from Manaphy, which will produce Phione eggs.
No, it's not true. Legendary Pokémon cannot breed with any Pokémon which includes Ditto except for Manaphy but Manaphy can only breed with Ditto and the Eggs that Ditto and Manaphy create will only hatch into a Phione.
All you need is Ditto. Catch one right below Goldenrod city then put Ditto and the legendary and just wait however the only Legendary Pokémon that's capable of breeding is Manaphy and the Egg that comes out when a Ditto and a Manaphy breeds will be a Phione Egg.
No you don't you can't get any legendary eggs you can get some like Rotom but you can only get a few legendary eggs search all legendary eggs on wiki.answers.com i got a rotom egg so it would work.
