New chick, eye problems

[WVchikinz]

Hello,
We just got our new flock of 8 chicks this morning. Everything seemed fine but this afternoon I noticed that one of my salmon faverolles had what looked like yellowish liquid on its back and the feathers around the eye. She's keeping one eye shut most of the time. We tried to clean it with warm water and a q tip.
Does anyone know what this might be or what we can do?
She was fine earlier and the other chicks don't seem to have any issues.
Thanks!

A follow up - she's not really eating or drinking. She stops every once in awhile and moves her head up and down slowly.

These hatched last night but one of them was stuck in the shell and I had to assist hatch. The only problem is an eye that will not open. I have just ordered some Renosan. Does anyone have any other tips of how to open up this little one’s eye?
