Yeah this is what I did for experimenting>>>
I hatched a level 5 Chansey and EV-train, highest stat gain was around... 11? 12.
I took that Chansey's mama out of the breeding centre, (it was level 40 already), and EV-train. I got a jump of 20. Lol...
So the bottom rule is;
~Pokemon don't gain EVs unless they get EXP from BATTLES. Not day care.
~~If you feel like seeing big stat rises, Day-care your Pokemon to level 90, EV-train then, and you can see stat boosts of like, 65, 70? Especially true with Rayquaza! Lol!
