Yep, it all sounds normal to me. With her just striking...sounds like she thinks she's a hot.

One thing I'd suggest is make sure that the rodent is good and dead before you offer it to her. I'd be afraid that with a rodent just stunned, since she's not coiling it and just striking it, it could come back concious as it's being swallowed and do damage to the snakes throat...dunno if it's possible, but that's what I'd worry about.
