I have been noticing a young pigeon, with some abnormalities in his beak. So after lots of trial today I finally caught him. When I opened his mouth I saw two small cheese like growth inside. And the upper beak is also covered with a growth. Is he suffering from both canker and pox? Also his butt is smeared with paste like poop, what do I do about it? His weight is around 150gm and he's a squeaker. I have metronidazole for canker, it's a suspension of 5ml=200mg. Please advise the dosage.
