I think we are blessed that Dakota came to us with a healthy diet. He is on pellets with millet treats and offerings of vegetables specifically leafy greens. Is an all pellet diet the way to go? He really loves his pellets - the zupreem naturals for cockatiels. He eats it all day. Sunny lived on a picky seed diet for over 20 years. I read conflicting info about pellets. I'd love to hear about what your tiels eat. Thanks! Here is Dakota eating organic lacinato kale.
