When my 3 kids were growing up, I did not have a lot of time to hunt & fish, but I would say the percentage was around 20 percent. When the kids all grew up and started their own families, the percentage grew to close to 70 percent.
I put up 100 to 150 lbs of crappie early in the spring, 100 to 200 lbs of catfish, and several wild hogs, as well as my limit of 5 deer almost every year. Every now and again I'll throw a Rib-eye steak or a chicken on the grill, but mostly it's deer burger, hog sausage, or baked or grilled fish at my house.
I do most of the cooking at my place because my wife works to late to start a supper when she gets home, and she likes the wild meats almost as well as I do. She never even went fishing until after we got married, and now I can't keep fish around her.
