VetRx is the avian VapoRub... it will help them breathe, but it won't cure what ails them. If it's truly a runny nose, and not just condensation or wet from just taking a drink, you will likely need to separate any showing the symptoms, and treat with Duramycin, Gallimycin or Terramycin. There may be others, but these are the three most common antibiotics that are easily found in your local feed store or pet store. Dosing with Tylan 50 injectable once a day for a week will help, too. I'm really tired at the moment, so I'm probably forgetting to mention something... I hope that someone will help fill in any blanks for me.
