When hogs and cattle are killed on a farm, the blood and other offal, and the small trimmings when the carcasses are cut up, should be saved and fed to the fowls regularly in moderate quantities, but care should be taken not to leave fat trimmings where the fowls can help themselves, for if fowls have been short of animal food, they eat meat very greedily and are often made sick by it. Blood and lean meat are not very injurious, but too much fat meat has very bad effects.
