I have a chicken that just took sick - help

[darlenelmyers]

one of my gold Spitz took sick over night and my vet does not treat chickens. She is was cold when I went out this morning so I brought her in the kitchen to warm but she is still listless and not very responsive to anything. I don't know where to start trying to help her.
I can provide more information if I know what I can provide that's more specific to help her.

Has she eaten/drank anything today? If not, what does the crop feel like on her?

How cold is it where you live? How old is your chicken? Can she stand or walk? Have you offered her any electrolytes or sugar water or food, and has she taken anything? Does she normally lay eggs? Does she appear to have any frostbite on her comb or feet? How does her crop feel—empty and flat, or full, hard, or puffy? Pictures may be helpful.

I am in NH so it got cold maybe 20's. They have not been laying recently but the heat lamp was in the pen and they have heated water. She does not look to have frostbite on her feet. She is laying on her side but occasionally will try to stand up with little success. Her crop feels empty. I just noticed she has a little bit of thick drool coming out of her mouth and nose. She drank water and looked better a hour ago but now can't even hold her head up. I can not find a vet available in my area that can treat chickens.
