Heat Stroke & Fever in Poultry

Hot weather can be deadly for poultry. Birds are highly sensitive to temperature changes, and extreme heat can lead to heat stress, heat stroke, and fever, causing sudden illness and even death if not managed properly.

Causes of Heat Stroke & Fever in Birds:

  • High environmental temperatures (above 35°C)

    Extreme heat can cause stress, dehydration, and lower productivity in birds.

  • Poor ventilation in poultry sheds

    Insufficient airflow leads to heat buildup and discomfort for the birds.

  • Overcrowding in cages or coops

    Limited space increases heat, stress, and the risk of health issues.

  • Lack of clean drinking water

    Without enough fresh water, birds struggle to stay cool and hydrated.

  • Direct exposure to sunlight without shade

    Unprotected birds under direct sun may overheat and become weak.

  • Stressful handling during transport or vaccination

    Rough handling in hot weather can increase stress and reduce immunity.

Tips for preventing birds from heat stroke

To prevent heat stroke in birds, ensure constant access to cool, clean water, proper ventilation, and shaded areas. Avoid overcrowding and reduce handling during hot hours. Using electrolytes and monitoring temperatures can also help keep birds safe and healthy in extreme heat.

  • Panting with open beak (gasping)

    Rapid breathing with an open beak as birds try to cool themselves.

  • Drooping wings

    Birds hold their wings away from the body to release excess heat.

  • Lethargy or weakness

    Birds appear tired, inactive, and unable to move normally.

  • Increased water in take but reduced appetite

    They drink more water but show little interest in feed.

  • Paleor bluish comb and wattles

    Discoloration indicates poor blood flow due to overheating.

  • Sudden rise in body temperature (fever)

  • In severe cases –seizures, collapse, or sudden death

    Extreme heat may cause nervous symptoms, unconsciousness, or even death.
