Gapeworm treated with Moxidectin Plus


In the Brooder

Hi all, we have a sick girl at the moment who we believe has gapeworm. She has been wheezy in her breathing and croaky in her voice. She has been mostly breathing normally (not opening her beak) but she has just spat up some mucus which we believe had red worms in it indicating gapeworm.

We have gotten her an appropriate dose of Moxidectin Plus from the vet but weren’t given any idea of how long the medication will take to treat her and for how long she will be showing these symptoms. If anyone as any information about the treatment of gapeworm with Moxidectin plus it would be most greatly appreciated. Thank you!

It would be best to call the vet and get the information you need.
Actually, gapeworm are rare in chickens. It would be best to submit a fecal sample from your hen that's showing symptoms to your vet for confirmation of gapeworm eggs in the feces. Also, if one bird has gapeworm, usually others will too.
Here's an excellent link for you to read about gapeworm:
It's possible your hen may have the onset of a respiratory disease which can mimic symptoms of gapeworm, possibly Infectious Laryngotracheitis (ILT) in which bloody sputum are a symptom. Again, other birds would be showing symptoms as well.
