The North American opossum (Didelphis virginiana) is a highly adaptable marsupial often found near human habitation, including chicken coops. These nocturnal omnivores are opportunistic feeders and scavengers. They will readily consume any available animal matter, including a severed chicken head. This behavior is driven by their nature as scavengers, seeking the easiest, most accessible food source.
The Opossum’s Omnivorous Diet and Scavenging Habits
The Virginia opossum’s diet is extremely varied, allowing it to flourish in diverse environments. Their natural diet consists largely of insects, small rodents, frogs, worms, plants, fruits, berries, and grain. They also consume carrion (dead animals), which is a significant part of their ecological role.
The presence of a chicken head is typically a sign of scavenging, not a successful hunt. While opossums can kill chicks, eggs, and occasionally weak adult poultry, they are generally less aggressive than other common predators. They are drawn to coops primarily by the scent of spilled feed, garbage, or accessible eggs, and they will consume poultry remains.
Opossums are not built for a clean kill, but rather for consuming food with minimal effort. Their jaws are not designed to cleanly sever the neck of a full-grown hen. Therefore, finding a chicken head separated from the body often indicates the opossum is merely finishing a meal started by a stronger animal or scavenging a carcass left by another predator.
Distinguishing Opossum Damage from Other Predators
Identifying the true culprit behind flock loss is necessary for effective prevention, as opossums are frequently blamed for damage caused by other wildlife. Opossum attacks are characterized by messy feeding patterns, often starting with wounds near the hocks or vent area of young birds. If an opossum kills a bird, the body is usually left behind with feeding signs beginning at the abdomen. They rarely kill more than one bird in a single event unless cornered.
Raccoons are known for their dexterity and often remove the heads of chickens by reaching through fencing, leaving the rest of the body intact. They may also consume the crop or leave dismembered body parts. Foxes and coyotes are efficient hunters who typically take the entire carcass away from the coop, leaving only scattered feathers.
Dogs often kill for sport, resulting in multiple injured birds, excessive dismemberment, or bloodied bodies with bites all over. A key physical sign of an opossum is its distinctive rear track, which shows a widely separated opposable thumb, unlike the tracks of canids or raccoons. Observing the feeding pattern, the number of victims, and the presence of tracks helps accurately determine the predator.
Securing Your Flock: Practical Prevention
Preventing opossum encounters centers on exclusion and sanitation, eliminating the easy food sources that draw them to the area. External food sources, such as pet food bowls and garbage cans, should be secured or removed before nightfall, as opossums rely on their keen sense of smell to forage. Securing the coop itself is paramount, as opossums can squeeze through surprisingly small openings (two to three inches).
The coop structure should be fortified with half-inch hardware cloth, not standard chicken wire, which is too flimsy and allows predators to reach through. Ensure all doors and access points are secured with predator-proof latches, as simple hook-and-eye closures can be manipulated. Burying hardware cloth 12 to 18 inches deep around the perimeter, or creating a two-foot apron on the ground surface, prevents digging predators from tunneling under the walls.
Motion-activated lighting near the coop can serve as an effective deterrent, startling the nocturnal opossum before it gains entry. Consistent nighttime confinement, where the flock is locked securely inside the coop from dusk until dawn, remains the most effective defense against all nocturnal threats.
