You're welcome to wait as long as you would like to breed your snakes. So much bull spread around about that. She's 1300g and a year old. She will be 1700+ before I even start pairing her at 17-18 months. I won't start pairing her until January. And she will go on a feeding terror to build when I start pairing her so she might hit 2k easily. Don't believe everything you read on the internet. I'm learning first hand that a lot of it is parroted bull crap. Some of the people that parrot the info haven't even bred a snake before! Overall there is a lot of good information out there but based on my experiences I would highly advise that you form your own opinions based on sound advice and your own experience. In fact, half the reason I don't post as much as I used to is because of the know-it-all attitudes that haunts almost all forums. It's more of a social clique than a information source and I'm sure someone is going to have a problem and/or dispute with what I just wrote. But I had three females all lay this season that weighed between 1200-1700g that started breeding at 17-18 months. I had one female that didn't go at 1300g. I also feed my snakes whenever they will accept food. There is a lot more to this discussion than some static line/size/age that most people try to dictate. This information is just a single example of one of the many fallacies that plagues keepers.
