I have a chicken (Buff Orpington about 8 months old) that sneezes a lot. This has been going on for weeks. There is clearly something wrong with her. She doesn't have anything coming from her eyes. When I first noticed this she was making a really loud noise when she breathed and I separated her from the rest of the chickens. That loud noise she was making went away after about a day. She does seem to be a little hoarse when breathing, but seems to eat fine. I have tried VetRx under her wings and in the drinking water with no improvement. I have 7 other chickens and haven't noticed anything wrong with them yet. Any advice on what I could do to help the chicken? Thanks in advance!
