It's been awhile now since I posted and during that time I have been diligently working with my little Sam to try to get her less afraid of us and more wiling to want us around and to not bite (a fair few painful pinches on our end to enforce our not going away policy ).
I think the last time I posted I was never able to get close to her or touch her without being bitten and she wouldn't even consider stepping up.
Now.....well its like she's a completely different bird. If I didn't know any better I would swear someone came and bird napped her in the night and replaced her with this sweet funny and cuddly feathery creature who just happens to look like my Sam. Roughly a week and a half ago she allowed me to stroke her head. Less then 5 minutes after she allowed me to do that she decided that it felt quite good and allowed me to give her strokes and scratches and pets all down her back over her wings and on her belly. As the days went by she got even more comfortable with me and my hubby and even started grooming us while we scratched and 'preened' her!
Then three days ago I was just scratching her belly after having unsuccessfully tried to get her to step up, and she raised her little foot and placed it ever so delicately on my finger, followed deliberately by the second one! If I hadn't been holding her I would have fallen over in shock. As it was, I was so shocked that I didn't click the clicker
But as the day went by, and I spent time with her spaced out over the day she got more and more confident about me and the prospect of my hand being a perch. She now steps up when I want her to, and even eats her piece of treat on my hand

She is still fascinated with fingernails and doesn't quite understand that they are attached quite firmly to me and that it hurts is she tries to take them off..
