I have bred females of all sizes and ages to me the important thing is the combination of both, I have had female bred at 18 months weighing at 1500 grams or more and I have bred 4 years old female at 1200 grams and it look like this season I am finally gonna be breeding a 5 years old female for the first time.
Yesexample a female ball python 1500 grams age 18 months...would you breed her??
