RE: Brit won't use her nose
Its good that the nose works,
As far as shooting over her, Slow down, back up, stop!
Dont get into a hurry, just get her to start finding birds. NO shooting, no CC, let her get birdy. Then work on getting her steady, then in a few weeks or months, when she is finding (Nose), and pointing, and is steady for the flush of the covey, start thinking about shooting over her.
