When Piggy and Ralph were at Castle Rock Roger pushed the boulder over the cliff and Piggy was killed when it hit part of his body and knocked him off the mountain forty feet on to a rock. That all happened in Chapter 11, Castle Rock.
Another answer: Piggy dies on the day that he and Ralph went to Castle Rock to demand the return of Piggy's glasses. This is the day before Ralph is hunted, the island is set on fire and the boys are eventually rescued. The boulder did not hit him on the head. The boulder actually struck Piggy a glancing blow, from chin to knee, which smashed the conch into a "thousand white fragments." Piggy traveled sideways through the air, turning over as he went. Piggy fell forty feet and landed, on his back, on the square rock in the sea. "His head opened and stuff came out and turned red. Piggy's arms and legs twitched a bit, like a pig's after it has been killed."
Piggy dies near the end of the book.
He is struck by a boulder that was released by Roger.
