My first clutch of balls was from an 18 month old het albino female. I feel body mass is more important. If she is a long slender snake than I would say no, but if she is short and stocky I would. I have females that will be lucky to max out at 2000 grams and others in the 4000 gram neighborhood. It's just their genetic make up that's why 1500 grams is not always a green light.
