i know a good grouse place in scotland... in angus.. not far from Aberdeen....and it has one fo the best and most productive and dedicated team of keepers and i think one of the beast grouse head keepers north of the border (thou the head man mayyyyy be slightly of his rocker ) and they have a guy separate from the keepers who catches rabbits all day every day and that's all he dose i fact he is the old head keeper.... simply because on a good estate a team of keepers dont have time for sleep let alone arseing about after rabbits
My first guess is Milden, my 2nd would be glen ogle??
