when comes to livestock in oregon pretty much all cities have ordinances against it if your with in city limits. Most will allow 1-2 hens as "pets" tho and most with purchase of a permit will allow 4-6 hens. Some cities like reedsport when comes to chickens don't enforce it as they feel they have alot better things to be doing than harassing someone about their chickens since most people now do have chickens their, It would be a never ending battle and just piss off more of the towns folk than it would please. Best bet would be to buy house somewhere right out of city limits tho and be 5-15mins from town, than you can do whatever you please basically.
When comes to predators their is a bunch. Hawks and owls seems to be biggest problem. Though weasels,raccoons,coyotes,bobcats,opossum,skunks do their fair share of damage too. The air predators seem to only kill what they can eat, where the ground predators will kill all your birds if given the chance so their the ones you really want to watch out for. Tho the hawks will learn where to get a easy meal and if you let them they will keep returning for more. Most the time the predators seem to be more of a problem very early in the morning. if you make a enclosed run with top cover and the sides buried 2ft in the ground you will probably be fine. if you dont bury the sides into the ground the ground predators will dig right under them and get in and if you dont have a top cover obviously hawks will have no problem getting in. I free range mine tho and i just got few jersey giant and copper maran roosters(really big boys) and they seem to do awesome job protecting the flock while being gentle giants too when comes to humans. the turkeys can be bullies to chickens sometimes and even get testy with humans but they work even better than the roosters they will chase off anything they dont recognize as being apart of the flock(they chase my cats off all the time and i have even seen them go after the neighbors dog and pig who like to sneak into the pasture and hangout with my cows).

Ever since i have added few turkeys and few roosters to my flock i have yet to have a problem as they get real loud and aggressive and most animals would rather just go find a easier meal else where. Also have couple cows that sleep in the barn where most my flock sleeps too so im sure that helps keep predators away too.
