The neighbours dogs came and attacked 3 of my hens thismorning, 2 were already killed, I disturbed them while they were going after this hen,and they ran off, but she has a nasty wound, and what looks like some missing skin. She cannot walk right now, I am not sure if the legs are broken, no visible injuries, it could be just shock but im not sure. For now she is inside in a box, I have sprayed some colloidal silver onto the wound. I don't know if I am deluding myself that she can be saved, I am so upset right now. Is there a chance, should I nurse her, or should she be culled. Any advice is greatly appreciated.
