i have a 4 month old chabo hen in quarantine at the moment...i could hear here wheezing when i walked outside this morning, both on in and out breathes, its very loud, then about once a min she does a big sneeze. but she has no other symptoms...no discharge from eyes, nose or mouth, no slimes, shes running around the cage as hyper as always, looking alert and bright eyed, eating like a horse and drinking fine....? had a look down her throat as far as i could see but couldnt see anything in there....do i treat as a URI or wait?? dont want to give anti b's if its simply a peace or straw or something stuck.....but dont want to wait to long incase she is sick??? advice please!
