Unfortunately, there is no way to put a dragon in storage after purchase or hatching. They only go there when they are won through a feature in the game (Spin to Win, Tournament, World Event). Also, a dragon can not go into the Dragon Stables from the nest, it must already be in a habitat to be placed there.

Sorry I couldn't be of any help... this is an issue many people have run into over the years. :(

Never played Castle Story and honestly between the DS wikia and FFS wikia I got my hands full. lol
