Twin chicks and "premature chick?" (help)

[Kiki]

alright so its opened it eyes but its still tired to it sleeps most of the time. i looked at its wing to sex it and its a girl! she's standing somewhat but she has very little balance. i've been giving her electrolyte and vitamin water through a medicine dropper but havent gotten her to eat yet. Everything going in the right direction but i think she has imprinted on me since shes separated from the mama hen so hopefully when shes better she'll be able to go with mama and get along.

Wing sexing mixed breeds does not work. You can only do this with certain breeds.

shes taken a turn for the worse sadly. shes not moving at all if any and shes deadweight when i hold or pick her up. She no longer wants to drink so ive been forcing carefully. she has this poop thats like diarrhea and then white and creamy. i just made her a nutri-drench water mix and started her on that and i also have a vitamin and electrolyte mix that ill be using as well. Her eyes are shut again and she dosent open them even though they are fine. ive brought her inside with a het lamp to better manage temperature and to monitor her better. Getting really worried, please help

Don't force anything at this age. One drop down the wrong pipe will kill it.
