it's great that she is acting so normally for you and not completely freaked out as expected. i have always waited a full week before feeding all newly acquired snakes except for one. it was feeding night for the others the day after i got her and as i was feeding everyone else she was pacing back and forth in her tub and worked herself into a total frenzy. i figured that she must smell the aroma of rat and decided to offer her one and see what happened. she struck it before i got it lowered all the way into her drawer. i guess what i'm trying to say is, if the snake is acting hungry and you are feeding the others anyhow you might as well give it a shot. she might just surprise you. maybe this new girl isn't going to be too much trouble to settle in after all.
