Hoarse guineas Please HELP

[Tricksy]

Dear Backyard chickens(and guineas), I hope there is someone out there that can help me . I'm sick with worry.About two months ago ,two of my guineas became hoarse then started breathing with their beaks open. When the first one went down I took her to the vet where she died. He did an exam found no gape worms or disease.he also did a fecal exam and found nothing.Poop seems normal. Activity leval normal. Everything normal except hoarseness and mouth breathing. The second one died one week later. Now two month later two other birds are hoarse. No mouth breathing so far. vet is hesitant to give antibiotics when we don't know whats wrong. Could someone please help me.I was a city girl from Cleveland ohio.Moved out to the country 4 years ago and know very little about poultry. Any help would be greatly appreciated. Thank You, Tricksy

You can try a process of elimination program. Put them on an antibiotic known to help with respiratory disease such as Gallimycin or Auromycin. If they improve you know you're dealing with a bacteria. If they don't then you know its a virus. Without some sort of tests to establish the disease its all guess work any way.

The next question is where did they come from and do you have other domestic birds?
