My bird sneeze and has mucus on the feathers around here cere?
I've brought her to an avian veterinarian a few days ago and was stated healthy. That means no infections or disease. She gave me a bottle of antibiotic as as stand by medicine. My Lovebird has sneeze 3 times now, can i give her antibiotics? It was advised to give her once a day for 5 days. Thanks in Advance.

Your bird most likely has a respiratory infection and certainly isn't healthy. I advise seeing a different avian vet. The one you went to sounds very incompetent. A qualified avian vet will give you the correct diagnosis and treatment (such as medication) for your bird. You will be told the correct amount of medication to give and how many times a day as well as how long to give the bird its medication.
