== Chronic Respiratory Disease == '''CRD''' is a disease that spreads very easy throughout a flock if left untreated. The first thing you need to do is isolate infected birds, as close contact spreads the disease. Then you have 2 options. You can cull infected birds, and burn the carcasses, or you can treat the symptoms. Keep in mind that a bird that has had CRD, will become a carrier after symptoms go away, and may get sick again when under stress. == Causes == Mycoplasma Gallisepticum bacteria. == Symptoms == * Rattle in the chest while breathing. (Sometimes the rattle doesn't show up until the birds are on the roost in the evening, and that is the best time to check for this condition.) * Bubbles in the eye. * Runny nose. * Coughing or sneezing. -''Not all symptoms need be present to have CRD, and if some of these symptoms are present, it is not a bad idea to isolate the bird, and treat for this before it gets worse, or spread throughout your flock. +Note: ''Not all symptoms need be present to have CRD, and if some of these symptoms are present, it is not a bad idea to isolate the bird, and treat for this before it gets worse, or spreads throughout your flock. '' == Treatments == * [[Tylan]] * [[Gallimycin]] * [[Baytril]] * [[LS-50]] == Prevention == Chicks that are exposed to these carrier birds may develop a natural immunity to CRD. == WARNING == '''Do NOT consume eggs from treated birds until at least 7 days from the end of treatments.'''
