Sick chicken, wont get up

[Clementine Coco]

Hello, Yesterday I found one of my hens laying in the coop and didnt seem to move, with like 85 degrees. I moved her inside the coop and gave her water while she layed down again. She was dehydrated and did drink a lot. (No idea how long she layd down outside) sinds than I moved her in a crate inside the house where its nice and cool. She refuses to stand up or walk, I dont feel an egg stuck, only thing she will eat is soft and watery food. She isnt paralized, seems like she falls asleep a lot, and closes her eyes.
Any idea what to do next?! She has been inside for 24hours now, eat and drinks good.
Need help! Thank you!

If you think the problem was heat, give her a cool bath. But they shouldn't be overcome by 85F. More likely it is a disease. Either viral, bacterial or fungal. Possibly protozoal, parasitic or environmental.
