My Dad always kept me in plenty of BB's and a working BB gun from when I was 6 years old until I graduated to a .22 at age 11.
Here were his rules:
1. NEVER point gun at anybody or anything you don't want to hurt.
2. NEVER bring a cocked BB gun into the house.
3. NEVER shoot anything but game animals and pests.
a) Quail, and doves are the only game birds you may shoot.
b) English Sparrows, starlings, blue jays, are all pests.
c) Robins, bluebirds, finches, hummingbirds, and woodpeckers are all
One day I strayed and shot a robin. Dad made me clean it and mom cooked the breast and then I had to eat it. it had a two tone breast much like a dove but much stronger tasting. In fact you couldn't tell much difference between it and a spotted owl.
