In a flock of broilers all sick and antibiotics aren't helping, what is the next best step?

• A. Quarantine the flock
• B. Water testing
• C. Switch antibiotics
• D. Necropsy dead birds

Answer: (D)

When birds in a flock are sick and antibiotics aren’t helping, the priority is to identify what is causing the illness rather than trying another drug. Performing necropsies on recently dead birds is the best next step because it provides direct information about the disease process. By examining tissues and organs, you can see characteristic lesions, look for signs of infection or systemic disease, and collect samples for laboratory testing (histopathology, bacteriology, virology, etc.). This helps distinguish infectious from non-infectious problems, determine if the issue is contagious, and guide targeted treatment, biosecurity measures, and management changes. Quarantining the flock can be important for containment, but it doesn’t tell you why the birds are dying. Switching antibiotics without knowing the cause can promote resistance and still fail if the problem isn’t bacterial or is a resistant organism. Water testing isn’t diagnostic for disease etiology in this scenario and won’t reveal the underlying pathology. Necropsy provides the most informative, actionable insight to steer the next steps in care and control.
