Well that hasn't happened to any trainer yet. Maybe you should give them time.
To my knowledge (not there yet) I assume eevee is male and evee needs to female to mate with ditto (as all pokemon)
Nothing. Since a Ditto can no breed with another Ditto. They will produce no egg.
Yes you always can get an egg if you breed with ditto.
No
you wont obtain a glaceon in the hatching process but you must put him/her in the daycare with ditto... Then you will get a egg, hatch it and you will get an eevee
no you cant
Ditto can breed with EVERY type of Pokemon except legendarys. Personally I JUST got an egg from the two of them.
You can find a Ditto egg in the Lab, in the Shelter, in the Egg Supplier. Sadly, Dittos can't be bred.
Yes, Feraligatr can breed and lay an Egg with a Ditto however it'll be a Totodile Egg.
Yes, any of Eevee's evolutions and a ditto can be bred for an Eevee egg.
A Dragonair and a Ditto will have a Dratini egg.
The female Pokemon can lay an egg, which will be another of the mothering Pokemon, but there's no way to get a Ditto egg.
