Something walking upright in Josephine County, Oregon

I recently moved into this house in May of 2004 and when exploring found different animal trails. Thinking they were deer, I occasionally follow them. After seeing that deer like to feed in the lawn area, I started putting apples and other fruit out for them. Within the last couple of months I have heard some things at night and when I checked I never saw anything but I always would smell a strong musky odor. The dog would go out barking; I knew he would come back in smelling like a skunk. He always came right back without a smell. When he went out chasing deer, he would always stay out for some time. I started to put fruit out on the table by the house. In the morning it was gone. A couple of nights ago I awoke with the motion sensor light coming on. I smelled that smell but by the time I got to my feet to look out the window all I saw was something large and dark walking on two legs, heading back into the trees. Unfortunately, the creature had moved into the shadows. The ground is solid so I have not been able to see tracks of anything, not even the deer that I do see crossing the property. I smell him almost nightly and continue to try to get a better look at him. I could not honestly tell if it was Bigfoot or a man but from where I saw him he was walking past a pull trailer and he stood with his shoulders well above the top. I am 5'5" and the trailer is taller then I stand. This is why I THINK I may have a Bigfoot around. I often feel like I am being watched. One last thing. When I first moved here, I had chickens and each night 1 or 2 would end up missing. There where never any feathers around so whatever took them carried them off. A coyote, racoon, skunk, etc. would kill at the site and there would have been feathers. I never did find any feathers, not even near the house.
