No, newborn rattlesnakes don’t have rattles. They develop a rattle as they start shedding. Please take this video down as I could have died as an 8 y/o kid because I caught a newborn rattlesnake because I knew that only rattlesnakes were poisonous in my part of the world. This misconception about rattlesnakes all having rattles regardless of age is very dangerous. Please take this video down and replace it with one that clarifies the information.
