I had a female that I purchased several years ago when she was only 4" and under 400 grams. She did not mate and produce eggs until she was about 6" and 900 grams. Now, over 5 years after purchase, she is 7" and 1100 grams, and has laid 8 eggs per year for the last 2 yrs. I also have a female that was purchased at about 6" and 900 grams who has produced 8 eggs per year.

The only male I've had that has successfully mated is about 5.25" and 600 grams. His son, who is closing in on 5" at 3 yrs of age, started showing interest in mating when he was about 4" and 2 yrs old. I don't have his weights available at the moment.
