I need help.

Last night, two of my mom’s chickens were attacked and we just found the rooster this morning. He was cold, but still breathing when we found him. Right now, we have him rolled up in a towel, and put him in a box with a heating lamp to keep him warm. He has some of his back head feathers torn out and he’s covered in dried blood. As for the hen, she’s currently M.I.A. As for what attacked them, we assume it was raccoons. Does anyone have any advice they could give me?
