This is Green muscle desease and not the result of poor storage or handling of the carcase.

Green Muscle Disease is a hidden problem in today’s large broiler chickens that is not detected until these birds are deboned at the processing plant. It is characterised by necrosis and atrophy of the deep pectoral muscle, which is commonly referred to as the breast tender (Bilgili and Hess, 2008). Green Muscle Disease is not a new disease, but it is becoming increasingly more common in meat-type broiler chickens selected for high breast meat yield.
