OK, I was just out in the coop and noticed one of my Speckled Sussex hens doing the CLASSIC gapeworm "silent crow" that I have seen described.  I've seen a couple of recommendations for some specific wormers, but someone also mentioned that Sulmet might work. 

Recommendations, anyone?  They haven't started laying yet.

How to treat gapeworm in a chicken? -


Flubendazole in feed, (levamisole. I think this medication is off the market in some areas
but Flubendazole is gotten at the vets

also read this carefully as if they have gapewroms you can see them in the throat

they are red and both the male and female make up the worm
they are shaped like a Y and stick in the chickens throat area

Syngamus trachea, a nematode worm parasite of chickens, turkeys, pheasants, and other game and ornamental birds occurring worldwide. Infection is by the oral route with earthworms, slugs and snails acting as transfer hosts but the life cycle may also be direct, by ingestion of embryonated egg or L3. There is an 18-20 day prepatent period. The condition is seen more commonly in poultry on free range where ground may be contaminated by wild birds e.g. from rookeries.

Gapeworms in the trachea of a Ringnecked Pheasant 
Scientific classification 
Binomial name 
Syngamus trachea
Montagu, 1811 
A gapeworm (Syngamus trachea) is a parasitic nematode worm infecting the tracheas of certain birds. The resulting disease, known as gape or the gapes, occurs when the worms clog and obstruct the airway. The worms are also known as red worms or forked worms due to their red color and the permanent procreative conjunction of males and females. Gapeworm is common in young, domesticated chickens and turkeys.

When the female gapeworm lays her eggs in the trachea of an infected bird, the eggs are coughed up, swallowed, then defecated. When birds consume the eggs found in the feces or an intermediate host such as earthworms, snails (Planorbarius corneus, Bithynia tentaculata, ), or slugs, they become infected with the parasite.

Ivermectin is a drug often used to control gapeworm infection in birds.

Treatment Medicines for ridding fowls of hairworms, tapeworms, roundworms and caecal worms can be bought from veterinarians or other suppliers. Carefully follow the maker's directions.

There are no effective treatments for gizzard worms or gapeworms.

Treatment for eyeworm can only be done by a veterinarian as the worm is removed under local anaesthetic.
Control You can protect your flock from serious worm infestation by:

feeding a well-balanced diet 
preventing feed and water fouling 
keeping your birds off fouled or damp ground or litter (worm eggs survive for long periods in damp, shaded areas) 
cleaning and disinfecting your poultry house regularly and thoroughly (particularly before you bring in a new batch of chickens) 
keeping chickens and adult birds separate 
raising chickens on wire mesh to reduce contact with worm eggs in droppings and with insects or other animals carrying parasites.
Carriers of worm parasites include:

earthworms - hairworm carriers 
grasshoppers, weevils and beetles - gizzard worm carriers 
slugs, snails, flies, ants and beetles - tapeworm carriers 
cockroaches - eyeworm carriers.
Control these pests when necessary but be careful to only use pesticides registered for the purpose; read and follow the label instructions including withholding periods. 

Regular treatment may be required for birds housed in heavily contaminated environments.

Birds or flocks infected with gapeworm should be destroyed or isolated from other birds to prevent contaminating the poultry house.

Hello. I had a question for you. I have been reading up on Gapeworm and believe my Rooster died because of this sickness. He had the familiar symptoms. I wanted to know if my other chickens are in danger of getting the same thing by sharing their perch together,  water and food?  Should I  clean clean out the Coop? Saw one of my chickens around the poo my rooster had been and even saw her cleaning his chest feathers! What should I do? Please help if you can. Thanks.  ")

yes gape worms are birds where infected bye gape worms x4. so I finaly got it wright I found some swine wormer with 1.8% fenabendazole plus tiger tourching my pens. that killed the egg's and the worms off stone dead. I went to entirely and type in the search bar swine wormer. it's in a 10 lb pale. mix grain and turkey feed in a cake pan put vegtable oil and put in two scoops of powder. mix it up so it all sticks together. and feed them for 7 to 8 days them birds will start doing back flips and that will stop picking as  it did for my birds.

Fenbendazole also comes in 10% liquid and 10% paste and is available at most feed stores. Just look for Safeguard or Panacur in the horse, cattle and horse sections of your feedstore.
