Nah, don't need any of them. I went on a breeding spree so I have at least 2 copies of the pokemon I gave you.
EDIT: Started to train you PIPLUP. *EXP Share* *Defeat level 15 Darumaka* *Grow 8 levels*
Also, you should of chose the Dratini, it had awesome egg moves (Ice Beam, Flamethrower, Water Pulse, Leer).
