I mean, I dont see why not? lol Here's what brought this question to being. I have a Cuckoo Marans rooster that when I put to bed that night he was fine, the next morn I walk out to find him gasping. (This was the second night of the hard freeze here in Fl). I listened to his lungs and seemed to be clear except you could hear the air flow through very well. He didnt cough at all, like he was choking. I looked as far down his trachea as possible and it was clear. When I have choking birds I always try the heimlic on them, altered for chickens, and sometimes its very successful. But it didnt work on him. I let him be and watched closely and he started turning blue and gasping seriously. I figured I was darned if I do and darned if I dont...I wanted to try the inhaler. I gave him a puff of my Xopenex HFA (Levalbuterol) inhaler (its like albuterol but the particles are more fine). Within 5 minutes he was walking around clucking, his color back to normal, still taking small breaths but not wheezing, and within 20 minutes he did not gasp at all and is still fine today. No remission. Not congested at all. I found it odd that the night before that I had had a mild attack and my cousin a serious one because of the cold air. Do you think its possible he had something similar?
