I have a sneezing chicken and I'm not sure which medication I should try. The only symptom is a raspy sneeze. No bubbly eyes and no discharge from the nostrils. I tried 3 days of soluble tylan (1 tsp in half gallon water), and I tried 2 days of Baytril ( .25 ml twice daily). There has been no improvement. Her energy level is good, she is eating good, there's just this pesky sneeze! She is separated from the flock. The only thing that changed a little is the sneeze has went from a raspy congested sound to more of a vocal sneeze. Before this happened my daughter was putting a dish of water out with ice and berries in it to help keep the chickens cool because it was hot. But the berries were sinking to the bottom. I told her to stop because if the chickens tried to get the berries from the deep water they might get water into their nostrils. Maybe my advice was too late? Could this be an infection and not a virus if something got lodged in the airway?? I also have tetracycline on hand. Any advice is really appreciated!!!! Please!!!!
