There is something going around my flock. I have been surfing the forums and still trying to find something that fits. Here are the symptoms they have. Not every bird has every symptom. Bubbles around eyes. Head shaking. Sneezing. Railing. Wheezing. They all eat, drink. All are active, all are chirpy, have normal poops. They ones that are able to lay eggs, lay eggs every day. They are alert, energetic. Someone I know said to smell their breath and that may be a bad sign if there's an odor. Any thoughts? I have tried Duramycin as directed. No change. I thought it was gape worm. All were treated orally with syringe and no change.
