how big to breed?

Ive heard different numbers... What is an ideal weight for female to reach before breeding?

The norm is usually 1500 grams and 2 years of age. This is not set in stone. Some may take much longer, and some can go at around 1200 grams if they are older - like 3-4 years of age).

I always strive for at least 1500 grams. It's better to take the time and do it properly than to rush it.

ok, i wanna make sure shes good an ready. i got pregnant at 17... dont want her to go thru that. lol

I bred a 4 year old that was just over 1,200 grams...don't believe I rushed anything at all. I also bred an 18 month old that was 1,800 grams...I may have jumped the gun on her, but she did just fine. I pay far more attention to my snakes' feeding habits and girth than I do weight.
