Weasels often attack chickens, preying on them by entering coops, killing them for food, and sometimes taking multiple birds in a single night.
Weasels are ruthless predators that can wipe out an entire chicken flock in one night. These small but deadly hunters kill by biting the neck and often leave multiple dead birds without eating them. Understanding their behavior is key to protecting your chickens.
How Weasels Kill Chickens
Weasels attack chickens with brutal efficiency. Their hunting methods differ from other predators, making them particularly dangerous to poultry.
Neck Biting Technique
Weasels typically kill chickens by delivering a precise bite to the neck. Contrary to popular belief, they don’t suck blood. Their sharp teeth puncture vital neck areas, causing quick death. You’ll often find chickens with:
- Severe neck wounds
- Nearly decapitated birds
- Minimal blood loss at the wound site
Killing Spree Behavior
Weasels often kill multiple chickens in one attack due to their:
- Instinct triggered by movement (flapping chickens)
- Desire to store food for later
- High metabolism requiring frequent meals
This explains why you might find several dead birds dragged to different corners of the coop. The weasel was likely trying to cache them for future meals.
Signs of a Weasel Attack
| Sign | Description |
|---|---|
| Neck injuries | Precise bite marks on neck/head area |
| Multiple deaths | Several birds killed in one night |
| Hidden bodies | Chickens dragged to corners or under objects |
| No consumption | Birds killed but not eaten immediately |
Why Weasels Target Chicken Coops
Weasels typically prefer rodents but turn to chickens when:
- Their usual prey becomes scarce
- They have kits to feed
- Your coop has easy access points
According to Backyard Poultry magazine, weasels are actually beneficial predators that help control rodent populations – until food becomes scarce.
How to Protect Your Chickens from Weasels
Fortify Your Coop
Weasels can squeeze through openings as small as 1 inch. Secure your coop by:
- Using 1/4 inch hardware cloth (not chicken wire)
- Burying fencing 12 inches deep to prevent digging
- Covering all gaps around doors and windows
Install Protective Features
Consider adding:
- Automatic coop doors that close at dusk
- Motion-activated lights to deter nocturnal hunters
- Electric fencing around the coop perimeter

Remove Attractants
Reduce weasel appeal by:
- Storing feed in sealed containers
- Cleaning up spilled grain immediately
- Keeping the coop area free of brush piles
Natural Weasel Deterrents
Some effective natural methods include:
Predator Urine
Fox or coyote urine around the coop perimeter may deter weasels. Reapply after rain.
Guard Animals
Consider getting a livestock guardian dog or even a goose to protect your flock.
Strong Scents
Weasels dislike:
- Peppermint oil
- Citrus peels
- Garlic
Place these near potential entry points as a natural repellent.
When to Call Professionals
If you’ve had repeated weasel attacks despite preventive measures, contact wildlife control experts. According to Critter Control, professionals can:
- Identify all entry points
- Set humane traps
- Provide permanent exclusion solutions
Understanding Weasel Biology
Knowing your enemy helps in prevention. Weasels:
- Have a high metabolism requiring daily food equal to half their body weight
- Can have delayed implantation pregnancies lasting up to 337 days
- Are solitary except during mating season
- Have territories spanning 30-40 acres
This explains their relentless hunting behavior and why they may return to productive hunting grounds like your coop.
