Dude,
Calves are probably the bitchiest of bitches!!!! They never seem to grow... I would however recommend you don't do them like 2-3 times a week... Once a week max... Never more than that... Also, do standing calf raises, donkey calf raises and seated calf raises... As heavy as possible... You may wanna begin your leg day with calves rather than quads or even do calves on another day to give them the attention they deserve!!!
A tip... Change the way you walk... Walk on your tip-toes around the house... On your way to the workout... In the gym... In fact, one calf exercise that people don't ever do and find funny, is walking around the gym on tip-toes with a heavy barbell across your back... I've done this, at the cost of people laughing at me, and seen fantastic results!!!
