I'd also vote for letting her settle in a bit before attempting your first feeding with her. She may well be a bit hungry as most breeders avoid shipping a snake that's just eaten and may skip her feeding that week of shipping to make sure she's not digesting anything. Being slightly hungry though isn't a huge deal for a snake. Remember these are creatures designed to get dinner when dinner is found and in the wild that's not every Thursday at 9 p.m. LOL. They are quite able to skip the occasional meal without any real harm to them.

Settle her in, offer her the same type of prey in the same feeding style she's used to in about a week and if she's hungry, she'll nail it fast.
