Chicken sick?

[Rach84]

Hi we got some chicks from a breeder yesterday. One is a bantam Wyandotte and is 4 days old. She looks like she is gasping for air and occasionally will cough / sneeze.
One of the 2 day old Austrolaup cross died last night too. I’ve done everything right with heating / food / water I’m just at a loss. The Wyandotte has been doing this behavior since we got home yesterday.
The other chicks are fine

Edited to add she raises her head / stretches her neck and almost sounds like she’s wheezing.

Sounds like some sort of respiratory infection such as MG (Mycoplasma Gallisepticum), Infectious Coryza or even Avian Influenza as that is going around. You can read about them here—

Since Avian Influenza is going around, I suggest looking into it. Avian Influenza Virus (AI) — https://drive.google.com/file/d/1jEgHBvYBXysmMGN--bJbzwTXHTg2pxIW/view?usp=sharing

Does she have discharge from her nostrils? Sorry to hear of your loss. I agree with @Myrshine in that it sounds a lot like a respiratory disease, as long as you are sure your air quality is adequate.
