Hi folks, Another post about my chickens with respiratory issues. Sneezing, coughing, and swollen sinuses are the most common symptoms. One of my chicks with a swollen sinus had been treated with doxycycline, but passed away last night. nasal flushing, hot compress, antibiotic eye/nose drops or doxycycline could not get her infection down. trying to save my others. Our vet did a swab and fecal, and two weeks later, the results are still not in. Part of the results are, and they specify no basic bacterial infection (though mycoplasma is not easy to cullture, so they don't know for sure that is out). We send out little one's body for a necropsy, but results won't be in for 2 weeks. meanwhile, I have tylan at home, and am considering ordering denegard. Cannot afford the vet anymore, and they really don't have experience with chickens. My guess is Mycoplasma G. or Infectious coryza. It could also be a virus, i guess, in which case it would be untreatable. Thoughts on whether Denegard or tylan would be a better option? or is baytril (pres. only) really the only way to go? i've read a ton of good things about denegard on this forum but really am looking for advice from folks with similar issues for whom denegard has worked, as i'm leaning towards that one. (or tylan, which i have at home now). Thank you in advance.
