Some BP's will eat often and lots, as long as she's growing I say feed her everything that she will take! Once they're adults you can worry about over feeding but at 1000grams your fine. I have a 600gram guy that eats small rats every 6 days. Just keep an eye out for space in between scales that's a good indication that she is over weight. Other than that be thankful that you have a good eater!
