I would first check with your department of game and find out if you would need a permit to have pheasants ... We needed one in Virginia.
They need to kept in a lot/run with a lot of cover to keep them happy, my husband cut cedar & pine trees to use. After a year and a half we sold the pheasants and went with quail. We keep the quail till it was time to renew the permit and then we had dinner ...
ringnecks are pretty but a pain to raise, i have red golden pheasants and they are much more pleasant, i keep a trio in with my pigeons and a pair in with my bantams, no problems, they don't like being caught but come when it's feeding time, you must keep them penned up or they will fly the coop, they aren't as cannibalistic as ringnecks
You should pick a more domesticated breed to keep. Wild type stay more or less wild & will roam away. Also, pick if you want roosting type or ground sleepers. I love Goldens, lady Amherst etc, but... My overall favorites are Silver. Much more tame than the others and very beautiful might I add. But, on the other hand... I LOVE waterfowl lol
