Can you post any pictures and describe her symptoms? How long has the chicken been sick? Is there any bubbles or foam in either eye, head shaking, swallowing of mucus in the beak, or rattly breathing? You posted a thread in 2020 about having a respiratory disease and do you still have any birds from that flock. Respiratory diseases such as MG and coryza can hang around a flock making them carriers. You may not see any outbreaks, but when there is a stress, such as during molting or freezing winter weather, there can be one that may she symptoms. If you describe all symptoms, we might be able to recommend an antibiotic. Viruses are sometimes milder, and can run their course over several weeks.
