Hello, andto BP.net...
Since the breeder that you got her from was feeding live, I would suggest that you continue feeding live for the next 5-8 weeks to get her established for you. Then, if you decided that you want to try frozen/thawed, you can start the process. You just want to make sure that she is feeding consistently for you first. Some snakes will switch over the very first time, with no problems, some will need some work, some just refuse to switch. I would also suggest that if your snake eats mice and you want to switch to rats, etc, do it before going F/T. Only make one switch at a time, which will give you a better chance of success...
