He's not that young. Already starting to get an iris. (actually its a she lol). weight isnt bad, bum was clean this morning. Checked it again just now and it had abit of poo stuck to it. COuld it be worms? Cause I treated them with ivermectin this arvo.He isnt quite as agile (a little clumsy climbing up the cage well) as the other bird (which is much older).
