I don't know that I'd try to force feed her anything, very easy to choke them. Just keep food and water in front of her, keep her warm and let her sleep a while. I had a chick that acted like that her first day home too. Very sluggish and droopy, just standing around with eyes closed. I made sure she knew where to eat and drink and parked her under the heat lamp. She slept all that day and all night. Next day she was fine. I think she had just gotten tired and cold. And sometimes a chick just isn't right and isn't going to make it no matter what you do. Could go either way.
