i just got a ball python 4 feet in length. i was told that it was going to be let go locally here in wisconsin witch would lead to her death and i just couldn't let them do that

i was told that it is 5-6 years old. the snake has been fed pinkies once a week its entire life. i was told that it is the reason that my snake is so skinny at its age. i want to work my way into frozen thawed mice/rats if possible. i need to know more about how to facilitate the switch or what my best bet would be so that i can get her eating a little bit larger meals and maybe get her to fatten up a little.

here is 2 pictures of her. she is small for her age from what i am told
