Are you feeding live, Pre-killed, or frozen/thawed?
Most people who feed live just toss the rodent into the cage. It is very important that you watch to make sure that the BP actually kills the rodent. Rodents should never be left unattended with a snake.
With Pre-killed and Frozen/thawed it depends on the snake. Some prefer a rodent on tongs, and some just want you to drop it in the cage. You will have to find what works for you and your BP. (I would start off with tongs)
