Offal from a poultry hatchery, including new-born chicks, is processed into a form suitable for rendering or disposal as land fill by dumping same into a device including a pair of elongated, generally cylindrical, counter-rotating rollers. Each roller has external longitudinally extending corrugations which mesh with the corrugations on the other roller. The corrugations are configured so that, as the offal passes between the counter-rotating rollers, new-born chicks and live, unhatched embryos are killed instantly and other debris, such as egg shells, are crushed into a smaller form.
