They really do grow at different rates, alot has to do with how picky or not they are with food. Obviously the more they are likely to eat, the faster their growth rate. Although this does not necessarily warrant more feeding for faster growth.

Two of my females, a pastel and mojave have totally different weights despite being about the same age. My pastel is an absolute pig amd will eat anything put in front of her. The mojave is picky and has only taken live although I have been working on converting her. The pastel is almost double my mojaves weight. Again it really depends on the snake.
