Most breeders say 1500g atleast for a female. 2 years old atleast. If your female was say 1500g. You cant just go by weight. Like the above post says if shes say 5 foot long. At 1500g thats to skinny. Now say 1500g at like 3 1/2 feet or 4 then maybe. I dont breed till mine are atleast 2000g. If they are fat enough, but not to fat. If they have enough size on them they come back better after breeding. Start eating sooner and get back up to size faster.
