I have a young pigeon that is holding his tail down and breathing heavily. His abdomen is swollen, I'm thinking the swelling may be swollen air sacs. But I also wonder if other internal swelling could be pressing on the lungs and affecting his breathing, He does not seem to be pooping much but I did see some watery discharge. A few months back a mature bird died quickly of a similar aliment at my place. Another adult bird recovered from similar symptoms with the help of Baytril. I have given this young bird one and a half drops of liquid Baytril 10 %. Please advise. I can be reached here, or by phone at 708-297-5493.
