- Sanitation: Regular cleaning and disinfection of housing, feeders, and waterers.

- Controlled Access: Limiting access to the duck area to essential personnel only.

 

Proper Nutrition

 

Providing a balanced diet tailored to the specific needs of ducks is crucial for their health. This includes:

- Fresh Water: Clean and fresh water available at all times.

- Supplementation: Adding necessary vitamins and minerals, especially niacin and vitamin A.

 

Regular Health Monitoring

 

Regular health checks and monitoring for signs of illness can help in early detection and treatment of diseases. This involves:

 

- Routine Inspections: Daily observation of ducks for any abnormal behavior or symptoms.

- Veterinary Visits: Regular check-ups and consultations with a veterinarian experienced in avian health.
