My d'Anver pullet, 3 months old, has had a cough and an open mouth, trouble breathing, for a month. I treated her for gape worm, wrongly, when she just hung her mouth open all day & scratched her ears. then finally I took her to the vet when she developed a strong cough. Here are her symptoms: General look of malaise, tired all the time. Opens mouth for air frequently. Appetite: Yes but scant. Craves fruits. Cough begins early afternoon, worse by late afternoon. Like a sharp bark or chirp. Goes away until sleep. Cough is sharp & frequent all lnight. Bird looks ill-rested in the morning. The vet I saw was a bird specialist, with experience treating chickens. She said she heard no rattle of mucus iin the chest, but that the throat was a little inflamed She prescribed two antibiotics, which seemed like a shot in the dark, and said she didn't know if this would do it or not. The vet put her on Baytril and doxycycline I dose her with Baytril 8 am & 8 pm, and doxycycline at noon. After a week, her cough is no better and she's losing a little more weight and looks worse. Any experience with this, anyone???? I don't want to lose her.
