Effort Values on hatched Pokesav pokemon

[PsychoBones]

So I think I know the answer, but I just want to make sure. If I put EVs on a pokesav pokemon that I want to hatch myself(IE: I clicked is egg), does the pokemon actually receive those EVs? For whatever reason I decided to use a cart that I hadn't gotten very far in to create the pokemon I wanted. While playing through that cart I just reached Sunyshore city and was unable to get an effort ribbon for any pokemon I hatched.
