We have an almost 4 month old pullet that has been sneezing and has nasal discharge. Shes healthy otherwise. She runs and plays and eats like the rest of our chickens. All the other chickens don't have symptoms like her. We bought some VetRX but we don't know how to use it or if its what she needs. Please if you know how to use it tell me and if you have any other ideas I would like to know.
