Sometime, our pets and our birds do crazy things that end up hurting themselves. This past week, one of our pullets seemed to get her head stuck to her detriment. I still am not certain where she did this, but the whole back side of her neck just below her head was bloody from one side of her face to the other. I didn't take photos because, in truth, it looked pretty bad and, well, yah. It was gnarly. It wasn't still bleeding when I discovered the injury but was still very red, albeit totally scabbed over.
I washed it off, best that I could without drowning her and then applied a bunch of Povidine, then isolated her for her own protection from the others.
Almost a week later, the scab is crumbling off, with only a small scab on the very back of her head (top of her neck) left. It still looks gnarly in the center of that scab, but her head feathers are covering it up so that it's not so obvious that she was injured. All the feathers are missing where the scab was originally, but, yah, it's not infected. The skin is healing and hopefully, soon, new feathers will grow back in place.
