Aspergillosis is a chronic problem caused by mold. There is no treatment for it except to remove any mold in the environment. Symptoms are rapid breathing, rather than deep breathing. Check her for an egg, by inserting a lubricated finger into the vent. I would put her back in the coop as Pwand suggested--maybe that will calm her down. Do you have a light in your coop to do it tonight? For the diarrhea, I would give her some probiotics in the form of buttermilk or Probios Dispersible Powder in the water.
