A few days ago a Yellow Golden Pheasant appeared in my yard and has not left (.75 acres in Northern California.) I checked with the neighbors and can't find the owner. I had planned on raising chickens and peafowls in the future, I guess this is my start. He, I am assuming he is male due to his bright plumage and long tail, seems content exploring and feeding in my yard. I have put out H2O for him and given him wild bird seed, which he likes. I have many potential predators in my area. What kind of aviary should I build for him? What should I feed him? Is it OK to let him roam free in the day and put him up for the night (he responds to voice commands)?
