Golden pheasants are easily kept. They aren't loud, even during breeding season. A good complete and balanced feed of at least 24% protein, should be fed, they also enjoy the occasional treat... BOSS, scratch in winter, unsalted peanuts and greens.
You can raise one male or have several in one pen if it is a large pen, ie; 20' x 30' they do better in trios or more, like 1 male to 4 or 6 females.
Everything will try to get to you're birds, so build a predator proof enclosure. In your area, hawks, owls, raccoons, coyotes, feral dogs and cats are the most likely predators.
A planted and landscaped aviary is best for the birds, fountain grasses, big smooth rocks, small shrubs, stumps, limbs are all good 'pheasant furniture'.
They can be tamed down considerably, if handled very frequently when chicks and juveniles. Although the may eat from your hand they are still 'wild' and will not 'free range', if one gets out or escapes, it will most likely not return and a predator will have it in a quick chilly minute.
Some can be fairly aggressive but most are not, at least not towards humans...they can be overbearing on hens though, that's why it's best to have 4 or 5 hens for every male and plenty of 'escape' places for the hens to get away from a overly aggressive male.
With alot of time, handling, and patience they can be tamed to make fair pets but never really become what I would call a 'pet'.
I have birds that are 13 years old...its not uncommon for Goldens to live 25 years in captivity.
