Begin with the flock, not the table
Record age, placement source, clinical signs, daily mortality, feed and water intake, recent treatments, vaccination and environmental changes. Note when the problem began and whether it affects the whole house or particular areas. A trend and a timeline are often more useful than one isolated number.
Make safety the first decision
Post-mortems should be performed by a veterinarian or trained person using appropriate protective equipment, biosecurity and disposal procedures. Sudden unexplained deaths or rapidly spreading disease require immediate veterinary advice and may require reporting to the relevant animal-health authority. Do not move carcasses or samples off the farm until the veterinarian or laboratory advises how to proceed.
Observe systematically and record
Select representative cases under veterinary direction. Start with the external condition and then examine body systems in a consistent order. Describe the location, distribution and appearance of findings rather than naming a disease too early. Photographs and written notes can help compare birds, but lesions alone may not identify the cause.
Use the laboratory to answer a question
Discuss sample selection, packaging, cooling and submission with the diagnostic laboratory before collection. The correct tissue and handling depend on the suspected problem and the test. Combine laboratory findings with history, examination and farm observations, then agree on immediate control measures and a follow-up plan with the veterinarian.
