Yes, chickens get ticks. Several tick species specifically target poultry, and infestations can cause anemia, reduced egg production, and even transmit serious diseases. Backyard flocks and commercial operations alike are vulnerable, particularly in warm and subtropical climates.
Tick Species That Target Chickens
The most well-known chicken parasite is the fowl tick (Argas persicus), a soft-bodied tick found on every continent. In the United States, the Argas group includes at least four species that feed on poultry: Argas persicus, Argas miniatus, Argas sanchezi, and Argas radiatus. These soft ticks behave differently from the hard ticks you might find on a dog. They feed quickly, often at night, then retreat into cracks and crevices in the coop to hide during the day. That makes them easy to miss even during routine flock checks.
Hard ticks can also latch onto chickens. In Australia, the paralysis tick feeds on chickens and other domestic animals. In North America, common hard ticks like the lone star tick or deer tick may occasionally attach to free-ranging birds, though chickens aren’t their preferred host.
Climate plays a major role in how severe infestations become. A study of poultry shelters in Pakistan found tick prevalence of about 39% across all shelters surveyed, with the hottest district (summer temperatures between 30 and 45°C) showing infestation in 52% of shelters. Cooler districts had noticeably lower rates. If you keep chickens in a warm, dry climate, the risk is higher.
How Ticks Affect a Chicken’s Health
A few ticks won’t cause obvious problems, but heavy infestations take a real toll. Soft ticks like Argas persicus feed repeatedly over their entire lifespan, from larval stage through adulthood. Each feeding draws blood, and when dozens or hundreds of ticks are feeding on a single bird, the cumulative blood loss leads to anemia. Affected chickens become pale in the comb and wattles, lethargic, and visibly weak. Egg production drops, and young birds can die from severe blood loss.
Beyond blood loss, ticks transmit diseases. The most significant is avian spirochetosis, caused by the bacterium Borrelia anserina. The fowl tick is the primary vector, and an infected tick can pass the bacterium at every single feeding throughout its life. Even more concerning, the infection passes from adult ticks to their offspring through the eggs, meaning the next generation of ticks hatches already carrying the disease. Avian spirochetosis causes acute illness in chickens and can be fatal without intervention.
Tick paralysis is another risk, particularly in Australia. When the Australian paralysis tick feeds, it injects neurotoxins through its saliva that gradually cause muscle weakness and paralysis. The toxins are similar in structure to botulinum toxin. Paralysis isn’t immediate; the tick needs to be attached for several days before signs appear, which in birds can include an unsteady gait and progressive weakness.
Signs of a Tick Problem in Your Flock
Because soft ticks hide during the day, you may notice the effects on your chickens before you spot the ticks themselves. Watch for birds that seem reluctant to roost at night, since they’re being bitten on the roost. Pale combs, weight loss, a drop in egg production, and general listlessness all point toward a blood-sucking parasite problem. In severe cases, you’ll find dead birds, especially younger ones.
To confirm ticks, inspect the coop at night with a flashlight. Check cracks in wood, joints in roost bars, and gaps between walls and nesting boxes. Soft ticks are flat, oval, and reddish-brown when engorged. During the day, look for their hiding spots by examining dark crevices closely. You may also see small dark fecal spots near where they shelter.
Treating Ticks on Chickens and in the Coop
Treating the birds alone won’t solve a tick problem. Because soft ticks spend most of their time off the bird and hidden in the coop structure, you need to treat both the environment and the flock.
For the coop, permethrin is an approved treatment for poultry housing and works against ticks, mites, lice, and bedbugs. It’s a synthetic version of pyrethrins, which are natural insecticides derived from chrysanthemum-like flowers. It works by paralyzing the insect’s nervous system. Apply it to cracks, crevices, roost bars, nesting boxes, and any joints or gaps where ticks could hide. Remove and replace all bedding before treating.
For individual birds, permethrin dust can be applied directly. Puff the powder into the feathers around the vent area and under the wings, where parasites tend to concentrate. Keep the dust away from the bird’s face and eyes, and avoid breathing it in yourself. A shaker bottle or squeeze bottle works well for application. Repeat treatments are usually necessary because ticks at different life stages may survive the first round.
Sealing cracks in coop walls and floors also reduces hiding spots. Smooth, well-maintained surfaces give ticks fewer places to shelter between feedings. In heavily infested coops, some flock owners temporarily relocate birds and leave the structure empty for several weeks after treatment, since soft ticks can survive months without a blood meal.
Can Chickens Control Ticks by Eating Them?
There’s an irony here: chickens are both tick hosts and tick predators. Free-ranging chickens do eat ticks they encounter while foraging. Studies in Africa found that chickens kept with cattle will pick off and eat dozens of ticks per bird from the cattle. However, researchers did not find that this meaningfully reduced overall tick populations in the environment.
Penn State Extension summarizes the evidence bluntly: chickens and guinea fowl feed on ticks but don’t eat enough to decrease tick populations. No controlled studies have been conducted in North America to measure whether backyard chickens reduce tick numbers on a property. So while your chickens will happily eat ticks they scratch up, counting on them as a tick control strategy for your yard isn’t supported by the data. They’re a snack, not a solution.
Which Flocks Are Most at Risk
Free-range and backyard flocks face the broadest tick exposure because they encounter ticks both in the environment and in their coops. Birds that roost in older wooden structures with plenty of cracks and crevices are especially vulnerable to soft tick infestations, since the ticks can establish large hidden colonies in the woodwork. Hot, dry climates favor fowl tick reproduction, and infestations tend to peak in summer months.
Flocks that share pasture with cattle, deer, or wild birds face a higher chance of picking up hard ticks from the environment. Young birds, sick birds, and broody hens that spend long hours sitting in nesting boxes are at greatest risk for heavy tick loads because they’re less active and less likely to dislodge feeding ticks through movement and dust bathing. Regular coop inspections, especially during warm months, are the most reliable way to catch an infestation early before it affects your flock’s health and productivity.
