I picked up a rooster yesterday and he was absolutely terrified when they went to catch him. He squawked a lot in the carrier while I was driving and, after I got him in his pen, I noticed he was rattling quite loudly. This was upsetting, to say the least. Well, the person I got him from happens to be a horse vet and I asked her to get me some baytril which she is. He's a beautiful boy and I hate to send him back as the living arrangements where he was kept was less than desirable. ANYWAY...this morning he wasn't rattling at all! I read that wet pox can cause rattling so I chased and caught him to see if he had any lesions in his mouth or throat. He didn't. Again, he was terrified and, when I let him go, I heard a little rattling - nothing like yesterday, though. Later, he was fine. SO MY QUESTION IS can stress cause a chicken to rattle when they breathe? I'm hoping that's all it is. I'm holding off on the baytril until I see if it happens anymore. I know that fowl pox is caused by a virus but his mouth and throat looked clean and healthy so I don't think that's what he has. Oh, and he acts perfectly normal, not sick at all. Thanks for your opinion!
