Fox got in the chicken area this morning and I just found out before it kills my babies. But one of my sweetest hen got attacked and stripped off her feathers. Back of the neck to tail part is gone. (It's not visible, I have to move other feathers to see her skin.) I checked her and no injuries anywhere, just feather loss. But my hen is down. She hides under the tree, close her eyes and her tail is down. She won't come out for treats, she just stay there. I understand what she went thru. Must be so scared. Is it normal to act like that after attack??? Even no injuries???
