Sudden Death Syndrome

Other Names: Flip-over Disease

Sudden death syndrome (SDS), also referred to as flip-over disease, is a heart condition commonly seen in rapidly growing young broiler chickens.

It is thought to be associated with a metabolic disorder due to the rapid growth rate and high carbohydrate diet.

Chickens will experience a sudden heart attack where they lose their balance and fall to the ground while violently flapping their wings. They often turn over on their back due to the violent flapping.
