History and Clinical Findings

Within a flock of 4-day-old broiler breeder pullet chicks on a farm in northeast Georgia, birds in 3 houses had an increased mortality rate. A representative sample of live and dead birds was submitted for diagnostic evaluation. Two of the affected houses had bird capacities of 10,800 birds, and the third had a capacity of 8,000 birds. At 7 days of age, flock mortality was reported to be between 2.24% and 3.8%. The chicks were observed to have neurologic signs of tremors, circling, and torticollis; evidence of ocular opacity and swelling; and lameness. At 14 days
