Silkie Chick with a "Cold"? What to do?

[Enchanted Sunrise Farms]

You are welcome. Hope she will be okay. It sounds like she will.

UPDATE:

Alright, so as of now her symptoms have not changed. She still sneezes even though she's only on paper towels...and I can't tell if she has rales or not because I haven't heard a chick with very obvious crackling while it breathes. Her peeping still sounds lower in pitch like her nose is stuffy, but I can't tell if that's from being sick or if it's just because she's 2 weeks old and her voice isn't so baby-ish anymore.

So, now what do I do with her? I'm not sure how long I need to wait for symptoms to worsen if they're going to, but from my understanding chick illnesses usually go faster than this

I'm really tempted to stick her back in with the others. She's been crying all morning even though the temp is fine, and I feel bad keeping her quarantined if she's not showing any other symptoms
