Chicken vomited water, has dark comb

[grammaC]

My hard-luck chicken, Dorothy, has been a bit lethargic, not eating, and her comb is starting to turn dark on the tips. Last Fall she was caught by a dog, but I was able to nurse her back to health, although she has a large area from a puncture wound that the others starting pecking again lately. She looks like she's moulting (they all are scraggly) and tonight when I picked her up and held he bottom up to inspect the wound, she vomited water. It was clear, and it smelled somewhat, though not super bad. I don't know what "normal" chicken puke smells like, so...

I think she may be dying. I brought her into the house to stay warm & un-bullied. Any ideas what the problem might be? What is a dark comb indicative of?

Oh, she's a year old RIR.

Darkening of the comb is a sign of dehydration. Check the bird's crop in the morning to see if it is swollen. It sounds like sour crop aka candidiasis. Here's some information about it: http://www.merckmanuals.com/vet/pou...ndidiasis_in_poultry.html?qt=sour crop&alt=sh
