I don't see any nasal or eye discharge that might indicate a respiratory illness. All of our chicks have sneezed, sometimes even there being small amounts of clear liquid flying out; I'm pretty sure now that this is due to high amounts of dust emitted from their bedding. If she starts acting lethargic and abnormal, then you might want to consider starting her on antibiotics. However, in my opinion, she looks fine, but you would know better than I do.
She seems fine aside from that. Nice and active talking a bunch eating and drinking. I contacted the lady i got her from and she says she hasnt noticed any of them sneezing or acting sickly. This little girl jas the largest nostrils i think she might be getting dust and what not in them when she is eating and scratching around. I keep watching her.
My chicks always sneezed when they were younger- not so much anymore. If she doesn't seem sick I think you're fine! there's probably just some dust floating around. Best wishes!
An active and otherwise healthy chick is a good sign. Like I said, we've have MANY little ones sneeze, but none have ever turned out to be sick. Enjoy your babies!
