Mink are one of the most destructive predators a chicken keeper can face, and trapping them near your coop is the most effective way to stop the killing. A single mink can wipe out an entire flock in one night through surplus killing, a behavior where it kills far more than it can eat, sometimes piling the dead birds neatly together. Setting the right trap in the right spot, with the right bait, is straightforward once you know how mink behave.
Confirm You’re Dealing With a Mink
Before you set traps, make sure a mink is actually your problem. Mink kill by biting through the skull or neck, leaving closely spaced pairs of canine tooth marks. If you find multiple dead chickens with small puncture wounds on the head or neck, especially if the bodies are stacked or grouped together, that’s a strong indicator. Raccoons tend to tear birds apart and eat organs. Dogs scatter and maul. A mink’s signature is precise bites and disproportionate carnage relative to what it actually eats.
Mink are small, sleek, and semifluid in their movement. Adults weigh roughly one to three pounds, and their long, narrow bodies let them squeeze through any gap their head fits through. That means openings as small as one inch in diameter. If you find a gap that size near your coop, you’ve likely found your entry point, and that’s also your best location for a trap.
Choose the Right Trap
Three trap types work well for mink, each with trade-offs depending on your situation.
- Body-grip traps (110 or 120 size): These are the most common and effective choice for mink. A 110 body-grip trap has roughly a 4.5-inch jaw spread, which is sized perfectly for mink. It kills quickly when the animal passes through, making it a fast-dispatch option. A 220 body-grip also works but is larger and poses more risk to non-target animals like cats. Stick with the 110 near a chicken coop where pets may roam.
- Cage or box traps: Live-capture traps are legal for all species in most states and let you confirm what you’ve caught before dispatching. They’re the safest option if you have pets, children, or free-ranging chickens nearby. The downside is that mink are trap-shy and may avoid entering a wire cage, especially if it’s new and carries human scent.
- Foothold traps (size 1 or 1.5): Longspring or coilspring foothold traps in size 1 or 1.5 catch mink effectively by the foot. They require more skill to set and conceal, and you’ll need to check them frequently since the animal remains alive and restrained.
For most chicken keepers dealing with an active mink problem, a 110 body-grip trap is the most reliable and practical option. It’s compact, inexpensive, and can be placed directly in a mink’s travel path.
Where to Place Your Trap
Mink are creatures of habit. They follow edges: walls, fences, foundations, stream banks. When hunting around a coop, they typically travel along the exterior walls looking for gaps or weak points. Place your trap along these travel routes rather than out in the open.
The best locations are:
- At the entry point: If you’ve found the hole or gap the mink uses to enter the coop, set the trap right there. A 110 body-grip placed flush against the opening forces the mink to pass through the trap to reach the chickens.
- Along the coop foundation: Mink follow walls. Set traps tight against the base of the coop, oriented so the mink walks through the trigger as it travels its usual path.
- Near water sources: Mink are semiaquatic and often travel along ditches, streams, or drainage areas. If there’s water within a few hundred yards of your coop, a trap set along the bank between the water and the coop covers a natural travel corridor.
A simple and effective setup is to create a “cubby set,” which is a small three-sided enclosure made from boards, bricks, or logs with the trap at the entrance and bait at the back. This funnels the mink through the trap and prevents larger animals from triggering it. You can lean two boards against the coop wall to form a V-shape, place bait at the narrow end, and position your 110 body-grip at the opening.
Bait and Lure That Work
Mink are carnivores with a strong preference for fresh meat and fish. The best baits include fresh fish (sardines work well and are cheap), raw chicken parts, or bloody rabbit pieces. The smell of blood and meat is what draws them in. You can also use the remains of a killed chicken if you’ve already lost birds.
Commercial mink lure, available at trapping supply stores, contains gland-based scents that appeal to mink curiosity and territorial instincts. A small dab of lure near the trap entrance, combined with a meat bait inside the cubby, gives you both a long-range attractant and a close-range motivator. Don’t overdo the lure. A pea-sized amount is plenty.
One effective trick is to drag a piece of fish along the ground from the nearest water source to your trap location. This creates a scent trail that guides the mink directly to your setup.
Check Traps Daily
Most states require you to check traps at least once every 24 hours and remove any captured animals. Virginia, for example, mandates daily checks for all traps except fully submerged body-grip traps, which allow a 72-hour window. Beyond legal requirements, daily checks are important for minimizing suffering and preventing non-target animals from sitting in a trap for extended periods.
If you’re using a live-capture cage trap, you’ll need to humanely dispatch the mink once caught. Most states permit shooting as a legal dispatch method for trapped animals. Mink are aggressive when cornered, so approach with caution and keep fingers away from the cage.
Legal Requirements Before You Trap
Trapping regulations vary significantly by state. Most states have a defined mink trapping season, typically running from late fall through winter. Virginia’s season, for example, runs December 1 through February 28. Outside that window, many states allow landowners to trap fur-bearing animals that are actively damaging property or livestock, but this exemption often applies only to the landowner personally, not to hired help or neighbors.
Some common legal requirements across states include tagging all traps with your name and address or a state-issued identification number, obtaining a trapping license or nuisance wildlife permit, and getting written permission before setting traps on someone else’s property. Body-grip traps under 5.5 inches can generally be set on land with or without bait. Larger body-grip traps may have placement restrictions.
Check your state’s wildlife agency website before setting anything. The penalties for illegal trapping can include fines and loss of trapping privileges, and regulations change frequently.
Seal the Coop After Trapping
Trapping solves the immediate problem, but another mink can move into the territory within weeks. The long-term fix is making your coop impenetrable. Mink can fit through any opening larger than about one inch, so standard chicken wire with its two-inch gaps is useless.
Use half-inch hardware cloth on all openings, ventilation areas, and run walls. This mesh is small enough to block mink and sturdy enough to resist chewing. Quarter-inch mesh, while tighter, uses thinner gauge wire that mink can actually break through more easily, so half-inch is the better choice. Cover the run walls at least two feet high with hardware cloth, and extend a buried skirt of wire at least 12 inches outward from the base to prevent digging underneath.
A concrete pad or concrete footings under the coop eliminate the digging threat entirely. Experienced chicken keepers who deal with mink regularly describe building their coops with cinder block foundations, hardware cloth on every surface, and locks on all doors and nest boxes. Every gap matters. Walk the perimeter of your coop at night with a flashlight and look for any point where light passes through. If light gets through, so can a mink.
