The 2024-2025 HPAI (Highly Pathogenic Avian Influenza) outbreak has devastated poultry operations across North America, with over 100 million birds affected since the outbreak began. As farmers face unprecedented biosecurity challenges, understanding how to identify, prevent, and respond to bird flu has become critical for protecting both livestock and livelihoods.
At Flight Control, we’re helping farmers implement effective bird deterrent strategies that serve as the first line of defense against disease transmission. This comprehensive guide combines our field expertise with the latest veterinary science to help you protect your operation from HPAI.
Understanding HPAI: The Current Threat Landscape
What is HPAI? Highly Pathogenic Avian Influenza is a severe form of bird flu that spreads rapidly through poultry populations with mortality rates approaching 100% in affected flocks. The current H5N1 strain has proven particularly devastating, affecting not just chickens and turkeys, but also waterfowl, raptors, and even some mammals.
How Bird Flu Spreads to Farms: The primary transmission vector is wild migratory birds—especially waterfowl like Canada geese, ducks, and other species that can carry the virus without showing symptoms. These birds contaminate farm environments through:
- Direct contact with domestic poultry
- Contaminated droppings in feed and water sources
- Shared airspace and facilities
- Contaminated equipment, clothing, and vehicles moved between areas

Early Detection: How to Know If Your Chickens Have Bird Flu
Rapid identification of HPAI symptoms can mean the difference between containing an outbreak and losing an entire operation. Here’s what to watch for:
Primary Symptoms in Chickens:
- Sudden death without prior illness (often the first sign)
- Severe drop in egg production (50-100% decrease within 24-48 hours)
- Respiratory distress: gasping, coughing, sneezing, nasal discharge
- Neurological symptoms: head twisting, lack of coordination, tremors
- Facial swelling, especially around eyes and wattles
- Purple discoloration of combs and wattles
- Diarrhea, often greenish in color
Symptoms in Geese and Waterfowl:
- Twisted neck and head tilting
- Loss of fear of humans (neurological impact)
- Swimming in circles or inability to fly
- Sudden death in previously healthy birds
- Discharge from eyes and beak
Critical Action: If you observe any combination of these symptoms, immediately contact your veterinarian and state animal health officials. Do not wait for multiple birds to show symptoms—HPAI can devastate a flock within 24-48 hours.

The Wild Bird Connection: Why Deterrence is Critical
While many biosecurity measures focus on limiting human access and cleaning protocols, the most overlooked vulnerability is wild bird access to farm areas. Research shows that:
- 85% of HPAI farm outbreaks can be traced to wild waterfowl contact or contamination
- Canada geese alone can carry H5N1 for weeks without symptoms while contaminating vast areas with infected droppings
- A single infected goose produces up to 2 pounds of droppings daily, potentially contaminating feed stores, water sources, and outdoor runs
High-Risk Wild Bird Species:
- Canada Geese: Large flocks, heavy contamination, attracted to farm water sources
- Mallard Ducks: Primary reservoir species, often asymptomatic carriers
- Northern Pintails: Long-distance migrants, peak transmission during fall migration
- Snow Geese: Massive flocks during migration, heavy farm area usage
- Various Shorebirds: Can contaminate shared water sources

Proven Prevention Strategies: A Multi-Layered Approach
Layer 1: Wild Bird Exclusion
Professional Bird Deterrent Systems are your most effective tool for preventing wild bird contact with domestic poultry. Flight Control’s methyl anthranilate-based repellents create an invisible barrier that trains birds to avoid treated areas without harm.
Strategic Application Areas:
- Feed storage areas: Prevent contamination of feed supplies
- Water sources: Eliminate shared drinking/bathing areas
- Outdoor runs: Create safe zones for free-range operations
- Perimeter areas: Establish buffer zones around facilities
- Equipment areas: Protect tractors, tools, and transport vehicles
Flight Control Max Application Protocol:
- Apply every 2-3 weeks during migration seasons (March-May, September-November)
- Reapply after heavy rain or irrigation
- Focus on dawn/dusk application when wild birds are most active
- Coordinate with other biosecurity measures for maximum effectiveness

Layer 2: Enhanced Biosecurity
Physical Barriers:
- Install bird netting over outdoor runs (minimum 2-inch mesh)
- Secure feed storage in rodent-proof, covered containers
- Eliminate standing water that attracts waterfowl
- Maintain vegetation to reduce attractive landing areas
Human Protocols:
- Dedicated footwear and clothing for poultry areas
- Hand sanitization between bird contact
- Vehicle cleaning before entering farm property
- Visitor restrictions during high-risk periods
Environmental Management:
- Remove spillage that attracts wild birds
- Clean waterers daily to prevent shared use
- Secure compost and mortality disposal areas
- Regular facility cleaning and disinfection
Layer 3: Monitoring and Early Response
Daily Health Checks:
- Morning and evening flock observation
- Egg production tracking
- Feed and water consumption monitoring
- Individual bird behavior assessment
- Mortality documentation
Environmental Monitoring:
- Wild bird activity tracking around facilities
- Weather pattern awareness (migration triggers)
- Regional HPAI outbreak notifications
- Veterinary communication protocols
Regional Risk Assessment: Timing Your Defense
HPAI risk varies significantly by season and geographic location. Use this framework to adjust your prevention intensity:
High-Risk Periods:
- Spring Migration (March-May): Peak waterfowl movement, breeding behavior
- Fall Migration (September-November): Massive flocks, juvenile birds
- Winter Congregation (December-February): Large groups at unfrozen water sources
High-Risk Locations:
- Atlantic Flyway: Major migration corridor, heavy waterfowl traffic
- Mississippi Flyway: Longest migration route, diverse species
- Pacific Flyway: Western operations, high waterfowl density
- Central Flyway: Great Plains operations, massive goose populations
Risk Indicators:
- Neighboring farm outbreaks within 6 miles
- Unusual wild bird mortality in area
- Heavy wild bird activity on property
- Weather patterns driving migration

When Prevention Fails: Response Protocols
Despite best efforts, HPAI can still reach your operation. Having a rapid response plan can limit losses:
Immediate Actions (First 2 Hours):
- Isolate affected areas immediately
- Contact veterinarian and state animal health officials
- Document symptoms, timeline, and affected birds
- Restrict all movement on and off the property
- Secure remaining healthy birds in biosecure areas
48-Hour Response:
- Work with officials on testing and confirmation
- Implement enhanced bird deterrent measures in remaining areas
- Review and strengthen biosecurity protocols
- Coordinate with neighbors on regional response
- Begin mortality disposal planning if confirmed
Recovery Planning:
- Complete facility disinfection protocols
- Wild bird exclusion system installation/enhancement
- Restocking timeline coordination with veterinarian
- Insurance and financial impact assessment
- Lessons learned documentation for future prevention
