I am new to the ball python thing and want to know that I am doing it right. I have heard-

DO NOT used live mice.
Use either pre-killed or frozen, etc. My question, is how?

Do I buy the mice and bash it in the head and then bring him to the ball?

Do I buy them ready-dead and frozen and thaw them?

I don't mean to ask stupid questions, but I want to make sure I am doing this right from the start.

Thanks!
