1. Isolate the sick zebra finch from other birds to prevent them from getting infected as well.
2. Monitor her carefully and closely observe any changes in her condition.
3. Provide a heat source to the bird cage. Zebra finches are native to hot, dry climates, and they need a temperature gradient in their cage to allow them to regulate their body temperature. You can use a heating lamp or a heat bulb to raise the temperature at one end of the enclosure, creating a warm area where she can perch if she needs heat.
4. Reduce the stress in her environment as stress can make the sickness worse. Try to keep the enclosure quiet and calm, ensuring there are no sudden changes or distractions that could scare her.
5. Soft food and plenty of fluids: Provide her soft, easy-to-eat foods like soaked seed, millet spray, and mashed fruits and vegetables. Make sure she has fresh, clean water available at all times, and consider supplementing with electrolytes to support hydration and electrolyte balance. Adding a bit of honey to the water can also be beneficial.
6. Maintain cage hygiene: Keep the enclosure clean and sanitized to reduce the risk of infection and disease transmission. Regular cleaning and disinfecting of the cage, perches, and food and water containers is essential. Remove any droppings, leftover food, or soiled materials daily.
7. Observe for any respiratory problems: Some respiratory infections can also cause discharge and swelling in the cloaca. If you notice signs of respiratory distress, such as wheezing, coughing, or labored breathing, it is important to address it immediately.
8. Consult a veterinarian: If her condition persists, it is best to seek professional advice and medical treatment. An avian veterinarian can examine the bird, provide an accurate diagnosis, and prescribe appropriate medication if necessary.
