I was away today and received a panicked phone call from my wife. Says the chickens were just attacked and to get home. She says she heard a commotion outside with the chickens running crazy around the yard and then noticed a "hawk" perched on the hen house and many dozens of crows flying around and perched on the fence and the neighbors house. The "hawk" was described to be what I think was a Peregrine falcon, and a little smaller than the chickens. There was an area next to the coop that had a larger than normal amount of feathers scattered around, but not sure what an attack would really look like if it got its talons into one of the chickens. None were bleeding or injured that we could tell, but were clearly shaken. We have let them have the run of the back yard since we got them in the Spring, but are fearful for them now. Thinking we should fence them in a little smaller area and put a netting over the top of it all. Should we really be overly concerned about the chickens being taken by a raptor here in Western Washington? We have three good sized Rhode Island Reds.
