I would f/f just because it makes delivery to hand so much easier especially when a water retieve is involved. This would also give you a handle to get her to pick the bird up. How have you disciplined her when she is acting like this? What happened just before she started doing this.
How badly does she sulk when you discipline her? Could this activity be a result of something she didn't like and is she retaliating?
