Most species will make little noises that sound like a door creaking. It's not as bad as some other birds I've heard, but they are not completely silent either.
I wouldn't recommend putting them with any other species of fowl. Pheasants have very different needs from that of a chicken. They need A LOT of space (It's recommended that you have 100 sq ft per pair), they need different feed, and the male's nice long tail will be ruined if put with other birds. Pheasants just won't thrive when put with other birds.
Also, pheasants are not, for the most part, friendly birds. You can't really hold them and they won't run up to you like chickens will (I've seen a few rare cases where they will, but VERY few.) You also can't free range them.
Pheasants aren't for everybody, but if you do careful research, you may find out they are the bird for you!
