You can't breed legendary Pokemon eggs on Pokemon SoulSilver or on any Pokemon game.
Legendary Pokemon do not breed, so they cannot lay eggs. However, only one legendary can breed, which is Manaphy. If you breed it with a Ditto, you will get the uncommon Pokemon which is 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.
You can breed Manaphy with a Ditto to get Phione.
no legendary Pokemon or genderless Pokemon can make eggs/breed. hope i help :)
No you cannot. Legendary Pokemon can't breed (make eggs). Not even with Ditto.
Most Legendary Pokémon cannot breed the only Legendary Pokémon that is capable of breeding is the Mythical Pokémon; Manaphy however it can only breed with Ditto and you will only get Phione Eggs and not Manaphy Eggs.
It's impossible to breed latios and latias.
latias dosent evolve cus its a legendary Pokemon
No, Legendary Pokemon cannot be produced by breeding. No legendary will produce eggs with Ditto, apart from Manaphy, which will produce Phione eggs.
You can breed any Pokemon capable of breeding with a Ditto. You cannot breed them with members of the no eggs group, legendary Pokemon or other Dittos. Actually You Can Breed Manaphy And Rotom (There Legendarys)
it is impossible except for when you have cheats in Pokemon pearl,platinum,diamond
No the only exeption is spiritomb only it can lay eggs
