My Buff Orpington rooster has some sort of respiratory problem. He is about 2 years old, and when he runs a little, or when I hold him near me, his breathing sounds hoarse. He also makes weird gurguling noises before and after he crows. I have been giving him fenbendazole for gapeworm, but I don't know if that is what he has. Can somebody tell me if they have ever experienced anything like this? Thanks.
