i,d feed her all the rabbits you catch for a bit and leave there jackets on ,that way she might look at it as she,s chasing food and not just chasing a rabbit ,ive had a couple of russels over the years that once they were broke to ferrets they wouldnt pick fur up but feathers they would smash them .have a think mate it could be something youve done along the way .but i think feeding her raw rabbit for a month or so would make her start to think after she,s missed her dinner ,but leave everything in and jackets on .its a shame realy sounds like she could have been a good dog but sooner or late
