What Predator Is Getting Into My Coop at Night?
What Predator Is Getting Into My Coop at Night?
You can usually identify the predator by the evidence it leaves behind. According to the USDA Wildlife Services program, the type of damage, entry point, and what remains (or does not remain) all point to specific predators, and knowing which one you are dealing with determines how to stop it.
In Santa Cruz County, the nighttime predators backyard flock keepers encounter most are raccoons, ringtail cats, foxes, weasels, bobcats, and coyotes. Each has a distinct pattern.
Raccoons are the most common coop raiders in our area. They are strong enough to open simple latches and can reach through chicken wire to grab birds. The telltale sign of a raccoon attack is a bird pulled partially through wire, or a bird killed and eaten only at the head and crop. Raccoons are also messy. You will often find scattered feathers and disturbed bedding.
Ringtail cats (sometimes called ringtails or miner's cats) are smaller and can squeeze through surprisingly tight gaps. They are present throughout the Santa Cruz Mountains, including right here in Boulder Creek. A ringtail can fit through any opening larger than about two inches. If a bird is killed cleanly with a bite to the neck and very little else is disturbed, a ringtail is a strong possibility.
Weasels (long-tailed weasels in our area) are the most alarming to discover because they kill multiple birds in a single visit, often biting at the base of the skull. If you find several birds dead with small puncture wounds and relatively little eaten, a weasel is likely responsible. Weasels can fit through openings as small as one inch, according to Penn State Extension.
Foxes typically carry birds away entirely. If a bird simply vanishes overnight with a small pile of feathers near the coop or run perimeter, a fox probably found a way in. Foxes dig, so check for gaps under fencing.
Coyotes and bobcats are less likely to enter a well-built coop, but they will exploit any structural weakness. A coyote can dig under a run or pull apart flimsy fencing. A bobcat can climb over a fence that is not covered on top.
The single most effective defense against all of these predators is half-inch hardware cloth on every opening, a solid floor or buried wire apron around the run perimeter, and predator-proof latches (carabiner clips or two-step latches) on every door. Standard chicken wire keeps chickens in but does not keep predators out.
This week: Walk your coop and run perimeter after dark with a flashlight. Look for gaps larger than one inch, check that every latch requires two steps to open, and inspect the base of your fencing for signs of digging.
