I've been reading a variety of resources and am struggling with what I should do. My chickens have developed a respiratory issue. I don't know what started it. I am guessing irritation from nesting materials, simple virus, or Chronic Respiratory Disease. I now have half my flock wheezing and sneezing. I want them to get better, but I don't want to jump to blanket treatment with an antibiotic if I don't have to. Can a chicken get a cold? If they do, can they get better without treatment? I'm reading many things that jump to antibiotic but... I just don't know about that... Arg. Throw it at me. What options do I have? Am I crazy for thinking that they might just get better on their own?
