Cerebellar Hypoplasia

Cerebellar hypoplasia and hydrocephalus is a neurological disorder of chicks. It is caused by inadequate development of the cerebellum and fluid pressure exerted on the chick's brain. The disorder is thought to be associated with the chicken parvovirus group.

Clinical signs of neurological involvement are noticeable soon after chicks have hatched, demonstrated by incoordination, paddling of the legs, and diarrhea.
