I am breeding a couple females this year with my son. I am looking to pick up a few more females soon with the intent to bring them up to size/1500 grams over the course of the year. How big should I expect a current 600, 900 or 1100 gram female to get in a year on a steady weekly diet of small rats?

The price is right vs what a breeder size animal would run me next year. Will they be up to weight by this time next year?
