I suggest dove hunting. Your season starts in 2 months. There is lots of shooting and generally alot more action than say quail, pheasant, chukar, or grouse hunting. Kids like action and shooting. They don't want to walk around for miles and only see 1 or 2 birds. On a good dove hunt, a kid can easily go through 2~3 boxes of shells. They're going to get a thrill out of trying to hit the birds and making the gun go bang. The limit's are pretty generous too, probably 12~15 birds a day. Also the ammo doesn't cost an arm and a leg.
