Great on the diet research!!! I don't feed pellets because I don't consider them the best option for parrots so I would suggest you might consider exploring other options because ekkies are one of those species which, even people who feed pellets to their parrots, would think twice about with them.
Now, I am not saying this to make you feel bad or anything but to prevent disappointment in case you are not aware of this. If you are, then just take it as me shooting the breeze. Parrots always are in their best behavior when they first come to a new house, we call it the 'honeymoon' period. So, use this time to bond with her and observe her body language -which is VERY hard with ekkies because they don't display like other parrots species- because, this way, when the honeymoon period is over, you will be prepared for her. It is entirely possible that she will never bite (I've taken in birds that never did change) but, if she does, don't think it's something you did or did not do, it's just that the honeymoon is over and, if you have ever been married, you already know how that goes
