Cannibalism is most common in over crowded birds, poor diet from low protein feeds, and is more common in the ringneck varieties than the ornamentals. The goldens are great and not all that skittish. just give them plenty of space. None of the ornamental are going to make pets by any means, they are wild birds, not chickens, but most are not flighty or crazy as long as YOU act right in their pens. Walk in, slow and steady, give them their space to move away, and all is fine. Planted pens help tremendously as well with calming them down, bare open dirt pens, leave them feeling vulnerable and thus more flighty.
Try some goldens or amherst, nothing more beautiful, and you'll love them!
Keep any pheasant way from chickens, not in a cage (8x 10 minimum per pair or trio), and dont try to catch them unless absolutly needed.
