Clinical description:
Velogenic viscerotropic Newcastle disease. Egg shell discoloration is one of the first signs of Newcastle infection involving the reproductive tract of the breeder hen. The dark brown shell on the left is normal, and the lighter one is affected. This sign is appreciable only in brown egg layers. If the infection is more severe, the shells become more fragile. Abnormalities in shape and size can also occur.
Pathologic description:
These eggs were both laid by birds that normally lay brown eggs. The egg on the left (brown) is normal, while the egg on the right (right) is abnormal.
