CRD is also called MG or mycoplasma gallisepticum. Symptoms can include watery eyes or bubbles in an eye, facial swelling, nasal drainage, sneeze or cough, and crackly breathing. Aspergillosis may cause silent gasping. Unfortunately there can be more than one disease present. If you seeing grey eyes and continuous diseases, you may need to put the sick chickens down. Aspergillosis and MG can cause grey eyes, and Mareks disease can as well. Lungs become scarred, and the chicken may always be sick and not productive. CRD spreads to other birds, and any new birds coming in will get it as well. Sorry about your chickens, but they are probably not going to get well even with all of your medications. Here is some reading about the two diseases:
