I know she's still young.But have you got her qaurtering?
if so, try working her on an embankment.Keep a few dead rabbits/birds in a game bag,Before setting her of quartering.First make sure you work with the wind in your face then.Pinch a bit of grass, spit on it and throw it to your left or right and set her away(This will help get her head down).When she's moving well bounce the game down the embankment without her seeing it as soon as she comes round and winds it she'll hunt like mad.Encourage her on, something like 'there lass'/'wheres it there' as this will help her later for blinds
