Your welcome and I hope that helps. You might also try some frozen corn cook it in the microwave. Chickens love corn and also give her a little grit to go with that. I think once she adjusts to her new house she will eat.
If she is in a cage or box put a mirror and a stuffed animal with her. Being alone she is probably confused. I would wet some chick starter and put it on a spoon and hold it up to her beak. I've never had a chick turn down mashed boiled egg. Tap it with your finger when you hold it up to her...
Please give us more information. Is the chick by herself or with a group of other chicks. What are the ages of the other chicks if you have them with her.
