We have a chinese golden/yellow - he is gorgeous, in our 19' X 20 ' pen (with chickens) and really not that flighty. No, I wouldn't let him out - and he is moving into his own run/shelter soon but only because we hope to find him a hen. I hear they get more aggressive once they have a female. But I have a friend with a farm and she kept pheasants with her chickens, no problem. The goldens ARE very docile though. And absolutely beautiful! I need to get a picture to post.
