I processed a rabbit and fed to offal to my chickens. Since there is only one rabbit and four chickens I gave it all to them whole. This type of food is perfect for omnivorous chickens. (Side note, I saw a carton of eggs the other day that said 100% vegan diet. Animal abuse!) Any offal they don't eat (who are we kidding, they devoured it) will draw flies that they will love to snack on.
