Cover the run to protect against aerial predators

Install a cover over the entire outdoor run to protect ducks from hawks, owls, and eagles. Ducks are highly vulnerable to aerial predators because most domestic breeds cannot fly and their instinct is to freeze rather than flee. Raptors are federally protected under the Migratory Bird Treaty Act, making lethal control illegal — a covered run is the only reliable defense.

Why It Works

Hawks and owls hunt from above by diving onto prey. A physical barrier eliminates their attack angle entirely. Heavy-duty bird netting (2-inch mesh or smaller, UV-stabilized) is the lightest and cheapest option for large runs. Hardware cloth provides maximum protection for smaller runs. Ensure the cover can handle snow load in northern climates or it will collapse during winter storms.

Tips

• UV-stabilized bird netting ($0.10–0.30/sq ft) is practical for runs over 100 sq ft
• Hardware cloth ($1–2/sq ft) is best for smaller runs under 100 sq ft
• Support netting with overhead wires or PVC pipe arches to prevent sagging
• Secure netting edges firmly — raptors can push through loose or sagging sections
• In heavy snow areas, use a peaked or angled frame so snow slides off rather than accumulating
