File an ERTS through the Department of Ecology. If this is near a salmon stream, it should draw some attention of Ecology, WDFW, and local code enforcement. An ERTS report will automatically send the complaint to all the agencies.

Well, I definitely just took a look at all of the places I'd normally expect to see address this in county code and came up pretty empty, so your best bet really is the state. Ecology and WDFW have the most teeth. Good luck.

When I lived in West Seattle I had a neighbor who raised roosters who crowed all day and night. It drove me crazy. I had a coworker who grew up on a chicken farm and knew all about chickens. He said their behavior wasn't normal and that it was extremely likely the neighbor was raising them for cock fighting. I eventually made a formal complaint to animal control and they sent a notice to my neighbor who immediately got rid of the chickens. Neighbor and his wife then started making death threats against me and my girlfriend. I ended up moving shortly their after. I really don't have a good solution for you but I do synthesize.
