One of our small mutt hens was attacked by a crow. She has what looks to be a partially slit throat, a little more than skin deep, she's breathing with her beak open, no gurgling or wheezing. There doesn't appear to be much bleeding but, her eyes are closed and I think there may be other internal injuries. Right now she's in a warm box. I don't know what to do next!!! Help, Gerbil.
