Hello, I had made a previous post about my rooster Mickey. He is about 7 yrs old and the family favorite. He has some sort of respiratory sickness, I'm thinking it is fowl cholera. We have given him duramycin-10( tetracycline hydrochloride) orally with a syringe twice daily for week with to no avail. The symptoms are the same. He acts fairly normal and eats, but the always sounds like he is gurgling. His crow also sound awful. He is separated from the flock, I'm going to give him a quarter of a cc of penicillin hopefully soon. Any other advice?? I appreciate our responses !
