Got preliminary results from the disease lab tonight: Gross Comments (July 1, 2013): The precise cause of death is not readily apparent based solely on gross necropsy examination. The lack of feed material in the crop and upper intestinal tract suggests that failure to eat likely contributed to death in this case. There is evidence of retained yolk sacs; however, there is no overt evidence of inflammation associated with the retained yolk sacs. It is unclear if the lung discoloration is real or an artifact of decomposition. Liver swabs have been submitted to bacteriology (chicks 6/29 and 7/1) to help rule-out an acute bacterial septicemia. Representative tissues will be examined microscopically following adequate formalin fixation. Histopathology and bacteriology are pending. The necropsy examination commenced at 1:17 PM on July 1, 2013. Examined are 3 chicks that are presented in individual plastic bags identified as 6/28, 6/29, and 7/1. Each chick has a pink band of the lower left leg. The chick in the bag identified as 6/28 is a gray male. The chick in the bag identified as 6/29 is a white female. The chick in the bag identified as 7/1 is a black male. The crops of all 3 chicks are empty. The 3 chicks have small and firm, yet retained, yolk sacs that vary from yellow to green-black. The coelomic cavities of all 3 chicks lack overt evidence of inflammation. The lungs of the chick in the bag identified as 6/29 are mottled red; the lungs of the chick in the bag identified as 6/28 are diffusely reddened. No gross lesions are identified in the oral cavity, external surface of the brains, heart, liver, kidneys, joints, or skeletal muscle of any bird. So no answers so far, but they aren't giving up yet! How sad that the splash was a girl.
