My chickens are still sneezing and coughing!!

[gaitnfool]

If anyone has any advice...I would sure appreciate it. I have 17 lovely ladies that I just adore. They started sneezing about 3 weeks ago. I started them on auremycin and had them on that for 2 weeks. They still have it. My vet knows nothing about chickens (according to him) and I am at a loss. I picked on of the ladies up and she was "gurgely"....as if she were really congested. Please help!!! Thanks.

What are you using for bedding? I have had birds sneeze if their bedding was too dusty, just a thought.
