Well, big coincidence in me posting in this thread today because I am here to say that the owl decoy does NOT work. Not even kinda. Had a hawk stalking my girls for a good hour.

And even I could not shoo it away! :/ The girls found some deep brush and are ok-there is a clump of feathers on the ground, so I am assuming it tried to grab one but couldn't, and I will check girls in morning, but they appear to be fine...so forget the owl. THey did well with deep brush, so maybe designate and area of the yard to something along those lines...oh and listen-they made a HUGE ruckus.
