I took my baby cockatiel (5weeks old ) out of the cage . He flew around the room and crash landed on the floor ,i thught that he was paralysed because he was not moving but after a while he started to move . When I touch his neck , he moans . He can hardly swallow the porridge that i feed him because it pains when he swallows . any idea what is causing this pain ? the bone under his neck seems to be sticking out more than usual .
