which says:
chicken and turkey coryza bacterial infections produce foamy, watery eyes, discharge from the nostrils, and sometimes swollen sinuses. Unlike fowl cholera, deaths rarely occur. Affected chicks and poults do not grow well, and the flock appears uneven in size.
Mycoplasma bacteria produce respiratory illnesses indistinguishable in most cases from chicken or turkey coryza.
Uncomplicated mycoplasmosis rarely kills affected birds, but serious secondary bacterial infections are common. These may result in death loss and, in the case of meat producing birds, condemnation of the carcass.
the treatment for both are antibiotics
I use aureomycin (another brand name of tylan) as there is no egg withdrawel, baytril is excellent but cant eat any eggs while treating or for 7 days after!"
maybe this could help you?
