Slimy clear discharge from mouth- 1 month old chick

[Chickenmom1228]

My one month old chick started today with slimy discharge coming from her mouth. She didn't want to be around the other chicks either. She isn't eating or drinking. None of the other chicks are showing anything signs. I already called a vet and they cant get me in till tomorrow. Her crop is empty, nothing feels stuck. I moved her to isolation. Any idea what it could be? Or what I can give her to help??
