You mean hatched into? Well, it depends on the Pokemon you bred. If you have a Eevee (any gender) with Ditto, since Ditto can breed with any Pokemon almost, they would make a baby Eevee Egg. If you don't have a Ditto then you would have to have a Male and Female Pokemon together in the Day Care. Wait for a few steps back and forth and you'll get a call from the Day Care Man and he'll let you know that there's a egg!
Hope this information helped!
