Green Muscle Disease (or Deep Pectoral Myopathy, DPM) is a degenerative disease of the minor pectoral muscles (i.e. the tenders), which is characterized by atrophy and necrosis. The condition arises when the muscle fibers become defi- cient in oxygen and is associated with sudden and excessive wing flap.
How do chickens get green muscle disease?
What Causes the Problem? It is believed that contraction of the breast fillet and the tender, the muscles responsible for the up- and-down strokes of the wings, is responsible for the problem. These major (breast fillet) and minor (tender) pectoral muscles account for most of the flight muscles in birds.
How do you prevent green muscles in chickens?
To reduce the incidence of DPM, it is important to minimize stress to the birds to reduce wing flapping. Pasture-raised chickens exposed to a variety of different stresses may need to be raised to a smaller weight to counteract the possibility of DPM.
What is deep pectoral myopathy in chickens?

Injury to the lateral pectoral nerve by accidental division, cautery injury, or avulsion produces variable postoperative atrophy, fibrosis, and shortening of the lower third of the pectoralis major muscle (PMM).
