Hi, a few weeks ago mine and my partners hahns macaw named Winston started with a sudden onset of laboured breathing, he seemed fine other than this breathing which was very loud. On the way to the vets it suddenly stopped but we still gave him his full course of antibiotics. Just yesterday the same thing happened, the loud breathing started and then stopped around an hour later, luckily we had some antibiotics left over from last time. He seems ok in himself, still eating and drinking, and talking! Does anyone have any ideas? He is 23 years old. Thank you in advance
