Flystrike is an extremely important topic for backyard chicken keepers to be aware of, but I’m going to warn you: it’s gag-worthy, so I promise to be as succinct as possible in covering the topic.

Flystrike is an extremely important topic for backyard chicken keepers to be aware of, but I’m going to warn you: it’s gag-worthy, so I promise to be as succinct as possible in covering the topic.

WHAT IS FLYSTRIKE?

Flystrike is a sanitized nickname for maggots living in and feeding on the dead skin of a live animal, which results in an infection. Flystrike can affect chickens, humans and other animals. Flystrike is also known as myiasis, blowfly strike and fly-blown. Whatever you call it, it’s nasty and can be fatal if not recognized and treated promptly.

Flies favor dark, moist locations for laying their eggs and while any area of the body can be affected, the vent area of a chicken is a fly favorite. Add stinky to the list of preferred fly aromas and a dirty chicken butt is a recipe for flystrike.

WHAT CAUSES FLYSTRIKE?

Many fly species favor dark, moist locations for laying their eggs and while any area of the body can be affected, the vent area of a chicken is a fly favorite. Add stinky to the list of preferred fly aromas and a dirty chicken butt is a recipe for flystrike. After the fly eggs are laid on or in the skin, the larvae can hatch into maggots in less than 24 hours; the maggots then begin feeding on the skin, causing deep, painful sores that can become infected. The most common flies responsible for flystrike are botflies, blowflies and screwflies. Occurrences of flystrike are most common in warm weather.

Chickens do a great job of maintaining their personal hygiene by dust bathing, however, runny droppings or chronic diarrhea that builds up on vent feathers can make it impossible for a bird to keep clean.

FLYSTRIKE PREVENTION

Chickens do a great job of maintaining their personal hygiene by dust bathing, however, runny droppings or chronic diarrhea that builds up on vent feathers can make it impossible for a bird to keep clean. A droppings-soiled vent area can cause the skin to breakdown, which may as well be a “vacancy” sign hanging in front of Hotel Maggot.
Following some of these suggestions can help reduce the risk of flystrike in chickens:

1. CONTROL FLY POPULATION

Keeping the fly population down can reduce the risk of flystrike. Read my article HERE for 15+ tips for controlling flies in and around the chicken coop.

2. MAINTAIN OVERALL HEALTH

The obvious recommendations are to keep chickens healthy by feeding them properly, keeping their coop and run clean and providing plenty of clean, fresh water. Probiotics can be added to the chickens’ water to maintain digestive health. Pay close attention to any injured areas on a chicken as healing wounds regardless of size or location are particularly vulnerable to flystrike.

Until any chronic droppings problem can be resolved, it is imperative to keep feathers underneath the vent clean to avoid flystrike. If droppings begin to accumulate beneath the vent, give the chicken a bath as described in this article. If feathers are impossible to clean thoroughly, carefully trim them off with scissors.

3. MONITOR DIGESTIVE HEALTH

Chicken droppings vary widely in texture, but consistently runny, watery, loose poop is an indicator of a problem. Diarrhea can signal a worm infestation, coccidiosis or a number of other illnesses. However, before rushing to treat chickens with anything, including purported “natural remedies,” the cause of the diarrhea must be identified. I recommend having a fecal float test performed when there are abnormal droppings. All veterinarians routinely perform these tests whether or not they treat chickens. Even if they don’t feel comfortable analyzing chickens’ samples, they can always send the sample out to a lab for you.

Spending time with backyard chickens and regularly inspecting them for wounds and dirty butts goes a long way towards avoiding flystrike.

4. KEEP VENTS CLEAN AND DRY

 Segregate the affected chicken from the flock to avoid the possibility of cannibalism. It should remain isolated in Chicken Hospital until the infection has healed fully.

5. PAY ATTENTION & INSPECT

Spending time with backyard chickens and regularly inspecting them for wounds and dirty butts goes a long way towards avoiding flystrike and detecting it early.

FLYSTRIKE TREATMENT

  1. Segregate the affected chicken from the flock to avoid the possibility of cannibalism. It should remain isolated in Chicken Hospital until the infection has healed fully.
  2. Offer the chicken vitamins & electrolytes in the drinking water for a day or two and keep her hydrated.
    Bathe the chicken, submerging the affected area in water, to assess the extent of the wound and drown as many maggots as possible.
  3. Bathe the chicken, submerging the affected area in water, to assess the extent of the wound and drown as many maggots as possible.
  4. Physically remove visible maggots in, on and surrounding the wound. Yup. Good times.
    Flush the wound with Betadine diluted in water or saline water. If the wound is very deep, use a syringe to squirt the Betadine solution into the cavity.
  5. Flush the wound with either Betadine diluted in water, saline water or Vetericyn spray. If the wound is very deep, use a syringe to squirt the solution into the cavity. (Peroxide is an acceptable substitute for the first cleaning or two, but don’t continue using it because peroxide can kill live tissue, preventing the area from healing properly.)
  6. Dry the affected area. If any of the feathers are in the way or preventing complete drying of the area, simply cut them. to dry it thoroughly afterwards. A hair dryer set on low heat can make quick work of it. Most chickens enjoy the spa treatment.
    Spray Vetericyn Wound & Infection treatment on the area affected by flystrike. This step may obviate the need for antibiotics in many cases of flystrike. Avoid ointments as maggots appreciate a moist, goopy, warm environment.
  7. Spray Vetericyn Wound & Infection treatment on the area affected by flystrike. This step may obviate the need for antibiotics in many cases of flystrike. Avoid ointments as maggots appreciate a moist, goopy, warm environment.

    Obviously, having a veterinarian treat the infection is the preferred course of action, but absent that luxury, most uncomplicated cases of flystrike can be managed at home.
  8. Repeat steps 3-7 two to three times per day until the maggots are gone and the wound is fully healed. Obviously, having a veterinarian treat the infection is the preferred course of action, but absent that luxury, most uncomplicated cases of flystrike can be managed at home. Should it become apparent that the infection is too severe to treat at home or is not responding to home treatment, a phone consultation with a compassionate vet can provide some guidance as to whether antibiotics or euthanasia are recommended. When fully healed, re-integrate the injured hen very carefully with this method.

Thanks for this information. I was at a loss on how to treat my hen. I now know how to prevent and treat next time it happens.

This is the first place I came when I discovered my hen had maggots on her rear end. She had recently suffered a prolapse that I had been treating per your advice. I put her back out, a bit too soon I see now, and a sore spot was attacked. I’ve been checking her several times a day, so I think I caught it soon enough. She is now resting back inside after following your treatment plan. Let’s hope she recovers quickly.
Thank you for all your wonderful suggestions and help.

I’m so glad I found this post! I thought our Patty was beyond saving and we were going to have to put her down. But decided to give it a week and try to get her better. After the week I was no longer finding maggots when cleaning her wounds (yes she had two wounds with HUNDREDS of maggots of all different sizes) puke! Within two weeks her wounds were scabbed over and she was getting cabin fever so I cut her loose from solitary confinement. But still monitored her wounds daily and sprayed Vetericyn on them. She healed tremendously… Read more »
