Cest Pharma’s Airway Drops for Pigeons are your number one choice for treating mild upper respiratory infections and congestion. Airway Drops contains an optimal mix of herbal extracts, all 100% natural, which aid in clearing the upper respiratory tract when pigeons sneeze or have blocked nasal passageways. Ideal for use during training and racing since they do not affect the bird’s conditioning or immune system. Formulated and tested by pigeon fanciers in Europe.
