Earlier this year, I had a rooster with mucus and yellow lesions inside his mouth that he eventually died from despite me trying to treat it. I used a fungal and canker medicine for pigeons which was all I could get at the time and also used gentian violet and veterycin spray. The lesions in his mouth grew so much they bulged his cheek out before he died. I never found out if it was a bacterial infection or canker or oral thrush. I now have what seems like the same problem AGAIN in my remaining rooster who is a huge buff Orpington, 5 years old and has been up till now in great health. His lesions are not yellow but white and don’t seem as bad as my first rooster. His breath smells bad. He is still crowing and eating and his crop is emptying but the mucus in his mouth is getting him down. Is it just coincidence that this is similar to what my first rooster had and if so does this mean it is canker? I have ordered metronidazole for pigeons in case it is canker but it has not arrived yet so in the meantime I have started treatment for thrush. I have been giving him over the counter thrush cream orally twice a day (which I never tried with my first rooster) and also swabbing his mouth and throat with betadine. I’ve been doing this for the last 5 days and his breath seems less bad but the mucus is still there as are the white lesions. I tried to remove the mucus with a baby nasal syringe but it didn’t work. Should I stop treating him for thrush and try antibiotics in case it’s bacterial? I just wonder how likely it is that 2 of my flock get bacterial infections 6 months apart. I have baytril if that is advisable. Just don’t know what to do next for my poor rooster and am feeling helpless. Thank you.
