No, there is a Mexican species that has no rattle. The Santa Catalina Rattlesnake or Santa Catalina Island rattlesnake (Crotalus catalinensis) is a species of venomous pit viper endemic to Isla Santa Catalina in the Gulf of California just off the east coast of the state of Baja California Sur, Mexico. The base of the tail, the "button", has degenerated to such an extent that the rattle immediately falls off with each shed instead of forming a new segment, as it does in other species of rattlesnakes.

Yes, hence the name rattlesnake. other types of poisonous snakes don't but rattlers do as a defense mechanism
No, rattles break off and hatchlings are rattleless.
