I've seen bald eagles here in Everett! Didn't think they came up here but one was perched in our broken tree.... Well, it was HUGE! Left the chickens alone.
I had a hawk though that tried to eat a broody's chick. They ran but the chick couldn't keep up, so she turned and chaced the sucker away all puffed out and meaning business. She did this twice and tried to flog the bird in flight. Bird didn't think it was an easy meal anymore and she walked away ticked and unscathed. No hawk problem since.
