I have a Japanse Bantam that has a problem. She has a lump on face, nasal discharge and a watery eye all on the same side. The other side of her face is fine. She eats and drinks fine and she is as peppy as the rest of the chickens when it comes to trying to catch. I have put Sulmet in her water and isolated her from the rest of my birds. Did I do right or do I need to do something else. Here is a picture.
