RE: Grouse Hunting in KY/Habitat
Hitting grouse is something you acquire with lots of bird hunting and even then its not always easy. I will say this. Grouse shooting is almost 100% instinctive/snap shooting.
As for habitat (in Kentucky), you want to look for secondary growth with plenty of thick edge cover. Pine thickets, blackberry brambles, etc are all areas that can hold grouse. Although birds can be found throughout most of eastern Kentucky, the farther east and south/east you go, the higher the bird numbers. My suggestion would be to go to Michigan or Wisconsin for a few days. Unless you know where there are some pockets of grouse in Kentucky, it may be a long (and dry) learning process for the dogs.
