As far as growth like any animal they'll have spurts. Though with reptile's temp does play an important role in their growth since your regulating their metabolism with the heat. You have to find the temp that works best for you as far as growth. Too high she'll metabolize it too fast and won't put on too much weight since she's burning it off like you would if you raised your metabolism with excersize. Too low and she'll either become too fat or her body may adapt to a low metabolic rate and stop gaining cause of that much like somone who plateau's on a diet or when trying to gain weight. Experiment and I'm sure in no time you'll be teaching somebody else a valuable tidbit of knowledge. As for the biting it could be the heat of your hand, the smell of prey if you've recently handled feeder's or rare meat, poultry etc. Or she may just not be used to it. Had a friend who barely opened his enclosure except to feed and rarely handled his snakes. He wound up getting bit alot. The snakes started associating the noise of the cage being opened with feedings, so were in s position the minute he started opening the cage. Personally I feed mine in a seperate tupperware container for 2 reason's. 1. this way they don't associate being taken out with food all the time. 2. I have several snakes co-habitating trying to breed them and this way there's no injuries while they're feeding. Snakes will bite snakes too you know. Hope this helps.
