I like the raspy old hen as well. After a bit of practice and patience you'll get it. Instead of sounding like a goose honking (that's what i sounded like at first), you'll start to sound like a hen talkin turkey!! I agree w/what was said above. Keep it soft and relaxed. I actually gave my husband a headache tonight while I was practicing!!
The sacrifices that you make when bringing your kids hunting with you, in the end, don't feel like sacrifes at all!
