I immediately used diatomatious earth on the food and a couple nights later I only heard one gurgle . I have some qiqerazine so I am using it. Ivermectin down the throat was recommended but I own Aussies so if they eat the feces after it could kill them so I am trying this. I thought having chickens roam free range was healthier but I guess it has its drawbacks. Hope yours get better and mine too. Sorry for the spelling I do not have the letter between o and q
This thread is almost a year old, you might get more and better responses/suggestions if you start a new thread. Sometimes if people see a thread is old they pass it by.
If your chickens are making respiratory noises, coughing, wheezing, rattling, or gurgling, and it's worse at night, they most likely have come down with a respiratory disease. This would be much more likely then gape worm. A course of antibiotic's will help get them over it. These diseases often go right into pneumonia and secondary bacterial infections, this is usually what kill's the bird rather then the disease itself, hence the need for antibiotic's. As well as keeping them warm, especially at night, until they recover.
DE (diatomatious earth) will not treat gapeworms nor help with any illness. It's an expensive product of little value but that's just my opinion. When you have an outbreak of anything, be it internal or external parasites, your much better off treating with something that is for sure going to solve the problem. You can use Safeguard to treat gapeworm if they did indeed have it, it's actually somewhat rare. I believe the dose for standard size chickens is a pea sized ball of the wormer per chicken for 3 to 4 days. I've never had to treat for gapeworm so double check that by doing a search on this forum.
Good luck with your birds, hope you are able to get them sorted out.
