Raposa, don't worry about Jenna being more comfortable with the breeder right now, after all she is feeding and taking care of her and she is going to favor her at the moment. But she will bond with you after you get her home and are with her every day, talking to her, feeding her and spending lots of quality time with her.
The wing clipping is a decision you will have to make for yourself but do talk to the breeder and get her opinion before you decide.
