I decide a female is ready to breed based on...

I can't vote as I do not breed, yet. I would like to some day. My little girl is a vey late '07 (december) and is 752g I made a graph of her wieght, and length growth and she seems to be growing well, she was 85g when I got her so,
This comming fall/winter she will be close to 1,500g (if she keeps growing as she has) but she would only be 2 years old.
I would have to say I personaly would wait one more year if I was going to breed her.
I also belive you should never breed any animal that is too fat/skinny.

But I do want to thank all those who do breed for helping inform all us noobs in the ball python world.
