Avian Encephalomyelitis (AE) disease can cause devastating egg production drop in laying hens. In breeders, the AE virus can be passed to offsping resulting in neurological disorders and mortality. When AE causes neurological lesions, it maybe described as "Crazy Chick Disease". Fowl Pox disease often results in poor growth and mortality in broilers, commercial layers and breeders. Fowl Pox infection also causes egg production losses in laying hens. Vaccination is applied through the wing web with an enclosed stabber. Comes in 1,000 dose vial.
