Do not put her back out. You need to give her at least 3 days of TLC, heat lamp, probiotic food and watch her poops. What I am seeing in your photo is not a normal chicken poop.
Give her AVC in her water, starter crumbles, yogurt and maybe some cooked egg.
Keep her warm, in a dim light and let her sleep.
