Is there a hole in the bottom of your chicken? If so, reach your hand up there and pull anything out. They may not even be present because things like gizzards, hearts, and liver are finding a market again. If they are in there, just rinse them off and toss them in with the chicken when you roast it. After they're cooked, either eat them whole, or chop them up and saute in some chicken fat with onions, mushrooms, etc. Mix with a little rice, and you have a side dish.
"Right is right, even if no one is doing it; wrong is wrong, even if everyone is doing it." - St. Augustine
