Gapeworm

[mom2minerchicks]

My one year old EE was diagnosed with gapeworm yesterday and started on Fenbendazole. She seems worse since I gave her the meds. She is coughing more this morning. Is that normal?

If it was me personally, I would probably do ivermectin first, then reasses.
Albndazole would be my first choice as a regular scheduled dewormer, but only because I have tons of the sheep drench already.

Two studies for everyone to read:

Anthelmintic efficacy of ivermectin against Syngamus trachea and Capillaria spp. in pheasant.

Abstract

Ivermectin (IVM) was perorally administered in dosage schemes 1 x 0.8 mg/kg of body weight (b.w.), 1 x 1.6 mg/kg h.w., 3 x 0.8 mg/kg b.w., and 3 x 1.6 mg/kg b.w. to pheasants infected by Syngamus trachea and Capillaria spp. The samples of faeces were coprologically examined. The clinical state of pheasant was controlled. In all of the used therapeutical schemes the helminthostatic or partially helminthocide effect against adults of worms was reached. The clinical signs of helmithoses were reduced only. IVM in tested doses is not possible to recommend as an effective drug of pheasant syngamosis and capillariosis.

Ivermectin as a bird anthelmintic--trials with naturally infected domestic fowl.

Oksanen A, Nikander S.
Abstract

To evaluate the use of ivermectin as a bird anthelmintic, 29 White Leghorn hens naturally infected with Ascaridia spp., Heterakis spp. and Capillaria spp. were treated with 0.2, 2 or 6 mg/kg intramuscularly or 0.2 or 0.8 mg/kg orally. Faecal samples were collected before treatment and at autopsy, 2, 6, or 16 days after treatment, when the intestines were also examined for helminths. None of the treatments gave satisfactory anthelmintic results.

It could be a die off reaction.
I'm a chicken noob, but a parasite expert.
When treating with meds and killing off a worm load, toxins, bacteria and viruses that parasites carry are released that will make one sick. Also, dead worms can cause a blockage, so you'll want to keep an eye out and make sure she is pooping.
Fenben is good.. Works to disrupt how parasites get energy, so it shouldn't kill off a bunch at one time, it does happen though. So, I'd lean more towards die off this early or medication side effect. If you can get her to drink some vitamin/electrolyte water, that might help. Ivermectin can produce nasty side effects too... Thats the worst of them all but least effective anymore.
Hopefully someone with more experience with chickens can guide you better.
I hope she gets well and makes a full recovery!

Did a vet diagnose her?

What is your recommendation for gapeworm treatment?

Yes, she was diagnosed by a veterinarian. Do I have to treat the entire flock?

Did the vet provide you with instructions how to treat for gapeworm, any info at all? Please post his/her instructions for everyone to read.
Internal parasites lay thousands of eggs onto your soil. Chickens constantly peck the soil and pick up unseen worm eggs. This is part of what's called the "direct" lifecycle of worms. The "indirect" lifecycle is when a chicken eats an infective host insect....much like a dog eating/swallowing a flea, then becoming tapeworm infected after the lifecycle is completed.
If I were you, I'd worm all my birds. If in fact it's gapeworm, you'll need a regular worming schedule in order to end the worms lifecycle.

I was given meds for 5 days for the infected chicken. I asked other questions ie. treating other chickens, separating the chickens, with no answer. She did have gapeworm eggs in her fecal sample. What is a good worming schedule?

I would treat the whole flock. What meds did they sell you? Panacur?

Here's a link for you to read. Scroll down abit and read about the gapeworm lifecycle. Honestly, it would be best to cull her to end the threat of eggs spreading on your soil, infecting your other birds.
