Hi. Your bird looks very healthy and vigorous, as do my two CAG girls. In addition to lots of regular toy changes, good diet with fresh fruits and veggies, calcium, challenging fun, I think the secret is how much they love and benefit by their daily evening bath. I put them on the top of the shower and spray them thoroughly with atomized warm water. They love it, and I think it accounts for their constantly improving appearance. Just curious to know if you shower (and others) your bird?
