a viral disease of chickens under six weeks old, caused by an enterovirus and marked by weakness of the legs followed by partial or complete paralysis of the legs, trembling of the head and neck, and degeneration of the neurons in the pons, medulla, and anterior horns of the spinal cord. Clinically, it resembles avian encephalomalacia and must be differentiated from that condition. Called also crazy chick disease and epidemic tremor.
