I want to thank everyone that gave me an answer,

i knew about the 10-15% rule for hatchlings till +/- 500 gram.

going by the rest of the answers it seems i have been doing ok, i have been feeding rats of about 70/80 grams 1 every 7 days unless she is in shed then she doesnt get any

1 other question, how likely is it she will be 1500+ by the end of this year if she keeps eating?
