Wondering whether worming chickens is easy? What are some all natural options? In this article, we’ll discuss the type of worms chickens can get, why they’re so dangerous, and what to do about it! 

Think about it: A chicken mama walks into her hen house to collect eggs. She reaches into the first nest and frowns. The egg has an unusual covering of chicken poop. This is not a massive problem. It just requires some extra cleaning. 
On to the next egg. It’s plastered with poop. The farmer begins to suspect something is wrong. Then, onto the third nest, where the prize-winner roosts. She is neat and tidy, and never leaves messes on her eggs. But chicken poop also covers this egg, and there’s some long white strands mixed in. 
Something needs attention, and she wonders what’s going on with her beloved birds. The list possible problems is a short one, and the solution is actually quite simple. These chickens have worms, and they need a better worming regimen.

What Are Worms Exactly?

Worms are parasites that can create health problems in chickens. Worms can cause lots of health issues, such as:
  • poor nutrition (because the worms are stealing vitamins and minerals from your flock)
  • internal bleeding
  • diarrhea
  • flightiness
  • pale combs
  • poor egg production
  • bloody stool
  • vision problems
  • death
You might also notice your hen doesn’t want to forage, and prefers to sit quietly in a corner.

How Do Chickens Get Worms?

A flock of chickens goes foraging, and might stumble upon a big, thick slug. It is a treat to the bird, but this yummy snack hides something insidious: a parasite. Your chickens swallow this parasite, and it finds a warm, comfortable place to live out its life cycle.
Chickens can also pick up worms from the soil, either by stepping on eggs, or ingesting eggs from dirt. Wild birds visiting their poultry cousins can also be a point of infection. Additionally, one chicken can effect her whole flock, since the worm’s eggs might infect her feces. Other hens might pick them up when walking around (which is why it’s important to clean your coop consistently)

What Kind Of Worms Do Chickens Get?

Chickens can get a variety of worms, including:
  • Tapeworms (Davainea proglottina and Raillietina cesticullus)  
  • Roundworms (Ascaridia galli)
  • Hair Worms/Capillary Worms (Capillaria obsignata
  • Gapeworms (Syngamus trachea)
  • Caecal Worms (Heterakis gallinarum)
  • Strongyle Worms (Trichostrongylus tenuris)
Each worm species effects chickens in different ways. But all worms are detrimental to your birds’ health. Most worms fall into two distinct classes.
  1. Direct – a chicken picks up these worms by scratching or pecking through contaminated feces. They spend their entire life cycles inside the chicken. Very often the eggs of these worms drop out of your chicken; they are quite durable and can hibernate for up to a year. Then, when another chicken picks them up, they then hatch, often by the thousands.  
  2. Indirect – these worms inhabit things that your chickens might have foraged. They might be hiding inside slugs, for example. Then, inside your chicken, they find a nice warm habitat to live out their life cycle. Indirect worms need a secondary host, such as an earthworm, before finding their permanent home inside your chickens
The following types of worms can infect your flock:

Caecal Worm

These are light grey to white in color and shaped like the letter S. They can grow to about ¾ inch. Caecal worms do not always show any symptoms in chickens. But chickens suffering a severe outbreak of these worms may look depressed or look worn out. The worms live in the ceca and have a direct life cycle. 

Capillary Worms

These worms are so small that one cannot usually see them with the naked eye. They are also called Hairworms or Threadworms. They live in the crop, intestines, and ceca, but in severe outbreaks, they can also inhabit the throat or the mouth. These worms are usually found in earthworms and slugs. A chicken infected by capillary worms will be weak and anemic. Their comb will pale, and the bird might appear emaciated. They also might suffer diarrhea. Extreme cases can lead to the bird’s death. They have both a Direct and Indirect life cycle. 

Gape Worm

Gape worms are red, and grow to ¾ inch in length. A male and a female lock together, resulting in a Y-shaped organism. Gape worms inhabit the trachea and lungs. They feed on blood get from micro blood vessels.  The most common symptom is a shortness of breath, often accompanied by a gaping beak, stretching its neck, and head shaking. The chickens will cough and frequently gasp for air and may also have a reduced appetite. They are Direct cycle parasites. 

Gizzard Worms 

These worms are very thin and grow to about 3/4 inch. They’re uncommon in chickens (far more common in geese). Symptoms include:
  • anemia
  • weight loss
  • diarrhea
  • a sickly appearance (might include a hunched posture and sagging wings)
This can lead to death if left untreated. They have a Direct life cycle.

Roundworms

Roundworms

Most common of the various worms that your chickens might contract. Roundworms are visible by the naked eye, and can reach lengths of up to 6 inches. Other symptoms can include:
  • Pale combs and wattles
  • decreased appetite
  • diarrhea
  • stunted growth
Extreme cases can also block the intestines, which can kill your bird. The infected bird will shed the roundworm eggs in her poop. Another hen can pick up these eggs, which will hatch in the new hen. Round worms have a Direct life cycle.

Tapeworms

Tapeworms are white, long, and flat. In chickens, they usually do not grow any longer than 13 inches. Segments of these worms can be visible in chicken feces – they look like bits of rice. Tapeworms live in different intestinal areas and feed on its host bird’s diet. As a result, the chicken will likely suffer an increased appetite, and will appear larger, primarily due to bloating. If a juvenile bird becomes infected with tapeworms, its growth could be stunted. Tapeworms have an Indirect life cycle; they need a host like beetles, earthworms, and other insects.

How Can We Protect Chickens From Worms?

Your chickens are very likely to get worms, especially if they live outdoors. This is a sad fact of life, but it is an important one. Stopping worms is not 100% about preventing worms from infecting your pets, but rather in minimizing the damageThe biggest risks are warm wet climates, and especially between late Spring and summer, when many parts of the USA endure heavy rains. Other areas of the country – the Pacific Northwest, for example – are ideally suited due to an almost year-round warm wet climate.
Worm eggs do not like extreme temperatures and go dormant in weather that is too hot for them or too cold for them. They are also averse to climates that are too dry to sustain them. To prevent a muddy coop, mix a good amount of stone, gravel, or having straight concrete flooring. This can reduce the number of active worm eggs in your flock’s home. 
Keeping grass short can also behoove a smart chicken owner. This helps to maximize the amount of UV light from the sun that reaches worm eggs. These eggs are particularly susceptible to UV light, and sunlight can destroy them. 
Be sure that your bedding is clean and dry. In wet weather, be sure to clean out your coop and chicken housing areas at least 2 to 3 times per week. If you use the deep litter method, and your chickens seem to constantly have worms, consider a different bedding option.

Should I Worm My Chickens?

Not sure if your chickens have worms? It’s easiest to collect some feces and take it to your vet. They can run tests to determine if and what kind of parasites your chickens might have. These tests are usually inexpensive. You’ll learn if your chickens actually need a worming regimen.
Worming regimens should not be year-long. You should do it only every so often (your vet can tell you how often). Parasites and chickens both can develop an immunity to the wormers. If this happens, it means you’ll have a harder time killing off this particular strain of worms. So, continuing to use it will have no effect. You can ask your vet about rotating options if you want to prevent worms. 

What Are The Best Wormers For Chickens?

There’s lots of opinions out there about what wormers are ideal. Some chicken owners might claim you only need natural solutions. Others insist that they are not enough.

If you can’t find Flubendazole, ask your vet about Fenbendazole. It’s a common medicine for goats, horses, dogs, cats, etc. Fenbendazole is usually sold in farm stores under the trade name Safeguard. Before proceeding, though it’s always best to ask your vet for dosage amounts.
