that and your cockatiel might get "Popeye Syndrome" and try to fight you

i am planning on getting a cockatiel pretty soon, definitely hand fed as a baby. i will have to try all those different foods like what you mentioned, i usually stuck with the cockatiel seed food with some veggies (carrots, corn, etc.)
