Cozzi is my 10 year old cockatiel. He started breathing with an open beak last week. I took him to the Avian vet, who said she thought maybe it was a lung infection. Put him on antibiotics and inflammatory meds 2x day. It has been 5 full days on the meds, and I haven't seen any improvement. I called the vet back this morning, she said she would do sedation, and get an X-ray and blood work. I am scared to death! Has anyone gone though this? P.S Cozzi is eating very good, and tries to play with his toys, but gets winded and panting when he tries to play. His weight at the vet was 85g, and since the meds he has gained 2 grams, but he still can't breath good.
