I have a 3-year old Buff Orp. roo, who, since he was a year old, has had breathing trouble. He gasps and has issues when he tries to crow, as well as has mucus in his nose and often drools. I know I have asked about my roo before, but recently the judge at a fair suggested bronchitis. Now, the only bronchitis I could fins on the Internet was infectious, and my other birds are not sick. So, is there a non-contagious form of bronchitis, and/or what do you think of Chronic Respiratory Disease? Thanks.
