Kids love dead things. I know when we come home with a bunch of fish or game, I have all the kids on the street over to check it out. Some of them even ask that I dont tell their parents.
Like said, if you dont make a big deal about it, neither will the kids. Let curiosity do its thing, and whatever you do, dont be afraid to let them get some blood on their hands!
My 11 year old son can fillet fish as good as anyone, and I now have a hard time cleaning any fish or game, because he wants to do it all.....god love him lol
