after looking at him tonight and checking his beak/mouth out it does appear the area may be coming back.. at least I was able to scrape off a thin sheath of white stuff again.. there was no visible growth or like it was but was able to remove a layer of white/yellow material from inside beak/mouth.. after doing so that area appeared raw/red looking and I put iodine on it then.. also gave him another couple drops of oral infant vitamins..let him out to stretch and run around and he acts totally normal.. pecking, scratching and purring around the place. still eating well.. now is the canker in the same family/treatment regime as the fungal stuff.. I am wondering about these fungal treatments and what to use/amounts/etc and if it would be safe to put in his beak/on his beak. i read in my chicken health handbook about various ointments and treatments for humans and pets for fungal infections such as athletes foot ringworm etc.. I am guessing they mean like tinactin foot cream- just not sure that would be good in his mouth.
