We have a hen who was attacked by something(I'm thinking a possum, since we have caught 5 in the past several months) and she may be going into shock. She is huddling in the tub we have her in and just standing there, and I have not seen her eat or drink. We do not have gatorade or powerade for electrolites and I was wndering if there was anything else I could do to prevent her from going into shock.
