my Quaker parrot rico is is 8 weeks old he is biting his feet lays flat on the bottom of the cage .since I got him I never seen him fly he flaps his wing streches one wing and leg at the same time . I only got rico for 5 day and I got him like that I think they sold me a sick bird . Rico is making a low popping sound is a a respiratory infection . He drinks his formula well eats his millet seed . So I am confused on what really is going on. I really need help I would like to see rico get well
