It is unlikely an 8 to 9 month old snake is 1058 gm. Be that as it may, 1058 gm is too small for breeding. I am not saying it can't be done, but it is IMO. irresponsible. The majority of those on this site will tell you that 1500 gm is a minimum to begin. Give her a year and see where she is at. The larger she gets the safer it should be for her.
At this size you may not even get a viable clutch or she could get egg bound. As she gets larger the probability of being viable is better, and you may get a larger clutch, so you would have more of a reward for doing things properly.
Patience grasshopper.
