If you are interested in experimenting you might try Golden Pheasant. I had some on my lease. I have no idea where they came from, likely escapees from somebody's aviary. They roosted up in the trees and bushes, they seemed more wiley than many Ringnecks. I've heard hybrid Golden and Ringneck makes a large bird that is really wild. Likely the traits that make them domesticatable disappear in the hybrid. I might have tried more Goldens if I continued my program.
