Week old baby chick sneezing...I think

[-Bella Cataline-]

I have a chick who appears to be sneezing. These are my first chicks so I'm unsure. All my chicks sneeze once in a while, but I'm noticing her sneezing often.
I wish I could attach a video of her doing it. How do I know if she's okay or not? If not, how can I help her? Thank you!

For video, UPLoad to YouTUbe and provide a link, the BYC upload does not work.

Photos of your brooder?
How's the ventilation?
How old are your chicks?
