Coryza is caused by bacteria so what you are doing is fine.I'm aware that they will always be carriers of the disease but the symptoms are supposed to go away and will usually only come back if the flock is stressed.

Infectious Coryza is caused by the bacterium Haemophilus paragallinarum and is seen in many countries especially in multi-age farms that are never depopulated. Morbidity is high but mortality low if uncomplicated although it may be up to 20%.
