Anyone familiar with swab testing chickens?

Most respiratory diseases can have secondary infections. It can be common for testing to show infectious bronchitis and mycoplasma, or coryza. E.coli can also be a complication and may cause air sacculitis. A necropsy when one dies is probably the best testing. Heat inside the coop, dusty conditions, mold, poor air circulation all can increase the probability of respiratory issues. During molting is a common time to see illnesses.

Thanks again. Mold and dustiness are definitely possible. Necropsies are quite expensive here. I haven't had any die with these particular symptoms anyway.

Just got the results of the respiratory panel back and my flock is positive for Mycoplasma gallisepticum. None of the other diseases were detected. If anyone has experience with MG in their flocks I'd love any advice and support.

I think I will treat Silvia, the hen with the worst symptoms, with another round of LA-200. Does that sound like a good idea?
