It could possibly be a cold, a respiratory infection, or even something like a respiratory virus (e.g., Infectious Bronchitis). It’s a good sign that she’s still eating and drinking, but you should definitely keep a close eye on her.
Here are a few things you can try at home:
- Keep her warm: Make sure she’s in a warm, dry environment, as cold stress can worsen respiratory symptoms.
- Use garlic or apple cider vinegar in water: Some people suggest adding a small amount of garlic or a teaspoon of apple cider vinegar to her drinking water. These are believed to have mild antibacterial properties and may help with respiratory issues.
- Ensure good ventilation: Poor airflow in the coop can contribute to respiratory problems. Make sure the coop is clean, well-ventilated, and protected from drafts.
- Monitor her closely: Watch for any other symptoms, such as nasal discharge, wheezing, or lethargy.
If she doesn’t improve or if new symptoms develop, it’s a good idea to contact a vet who specializes in poultry for an accurate diagnosis and treatment.
