I am suspecting it was a hawk or cat. We had them out, with our porch door open and my fiance ran out when he heard them freaking out. Our Easter Egger narrowly escaped, but we don't know what it was. She lost a bunch of back feathers, but no other visible areas were effected and no blood. We are freaked out and never going to let them out of our sight without a rock solid enclosure. Does anyone know what kind of animal could have done this?
